Fix CLI watcher cleanup race (#18905)
This PR supersets #18559 and fixes the same issue reported by @Gazler. Upon testing, we noticed that it's possible that two parallel invocations of file system change events could cause some cleanup functions to get swallowed. This happens because we only remember one global cleanup function but it is possible timing wise that two calls to `createWatcher()` are created before the old watchers are cleaned and thus only one of the new cleanup functions get retained. To fix this, this PR changes `cleanupWatchers` to an array and ensures that all functions are retained. In some local testing, I was able to trigger this, based on the reproduction by @Gazler in https://github.com/tailwindlabs/tailwindcss/pull/18559, to often call a cleanup with more than one cleanup function in the array. I'm going to paste the amazing reproduction from #18559 here as well: # Requirements We need a way to stress the CPU to slow down tailwind compilation, for example stress-ng. ``` stress-ng --cpu 16 --timeout 10 ``` It can be install with apt, homebrew or similar. # Installation There is a one-liner at the bottom to perform the required setup and run the tailwindcli. Create a new directory: ```shell mkdir twtest && cd twtest ``` Create a package.json with the correct deps. ```shell cat << 'EOF' > package.json { "dependencies": { "@tailwindcss/cli": "^4.1.11", "daisyui": "^5.0.46", "tailwindcss": "^4.1.11" } } EOF ``` Create the input css: ```shell mkdir src cat << 'EOF' > src/.input.css @import "tailwindcss" source(none); @plugin "daisyui"; @source "../core_components.ex"; @source "../home.html.heex"; @source "./input.css"; EOF ``` Install tailwind, daisyui, and some HTML to make tailwind do some work: ``` npm install wget https://raw.githubusercontent.com/phoenixframework/phoenix/refs/heads/main/installer/templates/phx_web/components/core_components.ex wget https://github.com/phoenixframework/phoenix/blob/main/installer/templates/phx_web/controllers/page_html/home.html.heex ``` # Usage This is easiest with 3 terminal windows: Start a tailwindcli watcher in one terminal: ```shell npx @tailwindcss/cli -i src/input.css -o src/output.css --watch ``` Start a stress test in another: ```shell stress-ng --cpu 16 --timeout 30 ``` Force repeated compilation in another: ```shell for i in $(seq 1 50); do touch src/input.css; sleep 0.1; done ``` # Result Once the stress test has completed, you can run: ```shell touch src/input.css ``` You should see that there is repeated output, and the duration is in the multiple seconds. If this setup doesn't cause the issue, you can also add the `-p` flag which causes the CSS to be printed, slowing things down further: ```shell npx @tailwindcss/cli -i src/input.css -p --watch ``` ## One-liner ```shell mkdir twtest && cd twtest cat << 'EOF' > package.json { "dependencies": { "@tailwindcss/cli": "^4.1.11", "daisyui": "^5.0.46", "tailwindcss": "^4.1.11" } } EOF mkdir src cat << 'EOF' > src/input.css @import "tailwindcss" source(none); @plugin "daisyui"; @source "../core_components.ex"; @source "../home.html.heex"; @source "./input.css"; EOF npm install wget https://raw.githubusercontent.com/phoenixframework/phoenix/refs/heads/main/installer/templates/phx_web/components/core_components.ex wget https://github.com/phoenixframework/phoenix/blob/main/installer/templates/phx_web/controllers/page_html/home.html.heex npx @tailwindcss/cli -i src/input.css -o src/output.css --watch ``` ## Test plan - Not able to reproduce this with a local build of the CLI after the patch is applied but was able to reproduce it again once the patch was reverted.

Document --watch=always in the CLI (#18337)
Closes https://github.com/tailwindlabs/tailwindcss.com/issues/1835 We had this in v3 as an undocumented option. We still have it in v4 but it's not documented under the CLI usage but should be. This PR adds this. **before** <img width="803" alt="Screenshot 2025-06-18 at 09 41 40" src="https://github.com/user-attachments/assets/c3becf11-e31d-4355-9d23-bddd0b2fc4a6" /> **after** <img width="1152" alt="Screenshot 2025-06-18 at 09 41 20" src="https://github.com/user-attachments/assets/4f61a156-680d-4f39-b92d-7f0f63270689" /> |

Add support for source maps (#17775)
Closes #13694 Closes #13591 # Source Maps Support for Tailwind CSS This PR adds support for source maps to Tailwind CSS v4 allowing us to track where styles come from whether that be user CSS, imported stylesheets, or generated utilities. This will improve debuggability in browser dev tools and gives us a good foundation for producing better error messages. I'll go over the details on how end users can enable source maps, any limitations in our implementation, changes to the internal `compile(…)` API, and some details and reasoning around the implementation we chose. ## Usage ### CLI Source maps can be enabled in the CLI by using the command line argument `--map` which will generate an inline source map comment at the bottom of your CSS. A separate file may be generated by passing a file name to `--map`: ```bash # Generates an inline source map npx tailwindcss -i input.css -o output.css --map # Generates a separate source map file npx tailwindcss -i input.css -o output.css --map output.css.map ``` ### PostCSS Source maps are supported when using Tailwind as a PostCSS plugin *in development mode only*. They may or may not be enabled by default depending on your build tool. If they are not you may be able to configure them within your PostCSS config: ```jsonc // package.json { // … "postcss": { "map": { "inline": true }, "plugins": { "@tailwindcss/postcss": {}, }, } } ``` ### Vite Source maps are supported when using the Tailwind CSS Vite plugin in *development mode only* by enabling the `css.devSourcemap` setting: ```js import tailwindcss from "@tailwindcss/vite"; import { defineConfig } from "vite"; export default defineConfig({ plugins: [tailwindcss()], css: { devSourcemap: true, }, }) ``` Now when a CSS file is requested by the browser it'll have an inline source map comment that the browser can use. ## Limitations - Production build source maps are currently disabled due to a bug in Lightning CSS. See https://github.com/parcel-bundler/lightningcss/pull/971 for more details. - In Vite, minified CSS build source maps are not supported at all. See https://github.com/vitejs/vite/issues/2830 for more details. - In PostCSS, minified CSS source maps are not supported. This is due to the complexity required around re-associating every AST node with a location in the generated, optimized CSS. This complexity would also have a non-trivial performance impact. ## Testing Here's how to test the source map functionality in different environments: ### Testing the CLI 1. Setup typical project that the CLI can use and with sources to scan. ```css @import "tailwindcss"; @utilty my-custom-utility { color: red; } /* to test `@apply` */ .card { @apply bg-white text-center shadow-md; } ``` 2. Build with source maps: ```bash bun /path/to/tailwindcss/packages/@tailwindcss-cli/src/index.ts --input input.css -o output.css --map ``` 3. Open Chrome DevTools, inspect an element with utility classes, and you should see rules pointing to `input.css` or `node_modules/tailwindcss/index.css` ### Testing with Vite Testing in Vite will require building and installing necessary files under `dist/*.tgz`. 1. Create a Vite project and enable source maps in `vite.config.js`: ```js import tailwindcss from "@tailwindcss/vite"; import { defineConfig } from "vite"; export default defineConfig({ plugins: [tailwindcss()], css: { // This line is required for them to work devSourcemap: true, }, }) ``` 2. Add a component that uses Tailwind classes and custom CSS: ```jsx // ./src/app.jsx export default function App() { return ( <div className="bg-blue-500 my-custom-class"> Hello World </div> ) } ``` ```css /* ./src/styles.css */ @import "tailwindcss"; @utilty my-custom-utility { color: red; } /* to test `@apply` */ .card { @apply bg-white text-center shadow-md; } ``` 3. Run `npm run dev`, open DevTools, and inspect elements to verify source mapping works for both utility classes and custom CSS. ### Testing with PostCSS CLI 1. Create a test file and update your PostCSS config: ```css /* input.css */ @import "tailwindcss"; @layer components { .card { @apply p-6 rounded-lg shadow-lg; } } ``` ```jsonc // package.json { // … "postcss": { "map": { "inline": true }, "plugins": { "/path/to/tailwindcss/packages/packages/@tailwindcss-postcss/src/index.ts": {} } } } ``` 2. Run PostCSS through Bun: ```bash bunx --bun postcss ./src/index.css -o out.css ``` 3. Inspect the output CSS - it should include an inline source map comment at the bottom. ### Testing with PostCSS + Next.js Testing in Next.js will require building and installing necessary files under `dist/*.tgz`. However, I've not been able to get CSS source maps to work in Next.js without this hack: ```js const nextConfig: NextConfig = { // next.js overwrites config.devtool so we prevent it from doing so // please don't actually do this… webpack: (config) => Object.defineProperty(config, "devtool", { get: () => "inline-source-map", set: () => {}, }), }; ``` This is definitely not supported and also doesn't work with turbopack. This can be used to test them temporarily but I suspect that they just don't work there. ### Manual source map analysis You can analyze source maps using Evan Wallace's [Source Map Visualization](https://evanw.github.io/source-map-visualization/) tool which will help to verify the accuracy and quality of source maps. This is what I used extensively while developing this implementation. It'll help verify that custom, user CSS maps back to itself in the input, that generated utilities all map back to `@tailwind utilities;`, that source locations from imported files are also handled correctly, etc… It also highlights the ranges of stuff so it's easy to see if there are off-by-one errors. It's easiest to use inline source maps with this tool because you can take the CSS file and drop it on the page and it'll analyze it while showing the file content. If you're using Vite you'll want to access the CSS file with `?direct` at the end so you don't get a JS module back. ## Implementation The source map implementation follows the ECMA-426 specification and includes several key components to aid in that goal: ### Source Location Tracking Each emittable AST node in the compilation pipeline tracks two types of source locations: - `src`: Original source location - [source file, start offset, end offset] - `dst`: Generated source location - [output file, start offset, end offset] This dual tracking allows us to maintain mappings between the original source and generated output for things like user CSS, generated utilities, uses of `@apply`, and tracking theme variables. It is important to note that source locations for nodes _never overlap_ within a file which helps simplify source map generation. As such each type of node tracks a specific piece of itself rather than its entire "block": | Node | What a `SourceLocation` represents | | ----------- | ---------------------------------------------------------------- | | Style Rule | The selector | | At Rule | Rule name and params, includes the `@` | | Declaration | Property name and value, excludes the semicolon | | Comment | The entire comment, includes the start `/*` and end `*/` markers | ### Windows line endings when parsing CSS Because our AST tracks nodes through offsets we must ensure that any mutations to the file do *not* change the lenth of the string. We were previously replacing `\r\n` with `\n` (see [filter code points](https://drafts.csswg.org/css-syntax/#css-filter-code-points) from the spec) — which changes the length of the string and all offsets may end up incorrect. The CSS parser was updated to handle the CRLF token directly by skipping over the `\r` and letting remaining code handle `\n` as it did previously. Some additional tweaks were required when "peeking" the input but those changes were fairly small. ### Tracking of imports Source maps need paths to the actual imported stylesheets but the resolve step for stylesheets happens inside the call to `loadStylesheet` which make the file path unavailable to us. Because of this the `loadStylesheet` API was augmented such that it has to return a `path` property that we can then use to identify imported sources. I've also made the same change to the `loadModule` API for consistency but nothing currently uses this property. The `path` property likely makes `base` redundant but elminating that (if we even want to) is a future task. ### Optimizing the AST Our optimization pass may intoduce some nodes, for example, fallbacks we create for `@property`. These nodes are linked back to `@tailwind utilities` as ultimately that is what is responsible for creating them. ### Line Offset Tables A key component to our source map generation is the line offset table, which was inspired by some ESBuild internals. It stores a sorted list of offsets for the start of each line allowing us to translate offsets to line/column `Position`s in `O(log N)` time and from `Position`s to offsets in `O(1)` time. Creation of the table takes `O(N)` time. This means that we can store code point offsets for source locations and not have to worry about computing or tracking line/column numbers during parsing and serialization. Only when a source map is generated do these offsets need to be computed. This ensures the performance penalty when not using source maps is minimal. ### Source Map Generation The source map returned by `buildSourceMap()` is designed to follow the [ECMA-426 spec](https://tc39.es/ecma426). Because that spec is not completely finalized we consider the result of `buildSourceMap()` to be internal API that may change as the spec chamges. The produces source map is a "decoded" map such that all sources and mappings are in an object graph. A library like `source-map-js` must be used to convert this to an encoded source map of the right version where mappings are encoded with base 64 VLQs. Any specific integration (Vite, PostCSS, etc…) can then use `toSourceMap()` from `@tailwindcss/node` to convert from the internal source map to an spec-compliant encoded source map that can be understood by other tools. ### Handling minification in Lightning Since we use Lightning CSS for optimization, and it takes in an input map, we generate an encoded source map that we then pass to lightning. The output source map *from lighting itself* is then passed back in during the second optimization pass. The final map is then passed from lightning to the CLI (but not Vite or PostCSS — see the limitations section for details). In some cases we have to "fix up" the output CSS. When this happens we use `magic-string` to do the replacement in a way that is trackable and `@amppproject/remapping` to map that change back onto the original source map. Once the need for these fix ups disappear these dependencies can go away. Notes: - The accuracy of source maps run though lightning is reduced as it only tracks on a per-rule level. This is sufficient enough for browser dev tools so should be fine. - Source maps during optimization do not function properly at this time because of a bug in Lightning CSS regarding license comments. Once this bug is fixed they will start working as expected. ### How source locations flow through the system 1. During initial CSS parsing, source locations are preserved. 2. During parsing these source locations are also mapped to the destinations which supports an optimization for when no utilities are generated. 3. Throughout the compilation process, transformations maintain source location data 4. Generated utilities are explicitly pointed to `@tailwind utilities` unless generated by `@apply`. 5. When optimization is enabled, source maps are remapped through lightningcss 6. Final source maps are written in the requested format (inline or separate file) |

Write to log file when using DEBUG=* (#17906)
This PR improves the debugability of the scanner when using `DEBUG=*` by
writing to a `tailwindcss-{pid}.log` file in the current working
directory.
It will include all the tracing information from the scanner. This PR
also introduces `Discovering {path}` and `Reading {path}` logs.
- `Discovering {path}` — this is logged when we are traversing the file
system looking for files. We use the `ignore` crate, and log this
information in the `filter_entry` callback. If a file was already
ignored by `.gitignore` files, this won't show up, but it also means
that we will not read it.
- `Reading {path}` — this is when we are actually reading the file so we
can start extracting potential Tailwind CSS classes.
These will give you some insights in what paths are being scanned, and
if we get stuck, where we get stuck.
Also, we are appending to the file. In the log below, you can already
see that a `tailwindcss-<number>.log` file exists already even though it
didn't exist before running the command. This should make it easier to
debug if we get stuck on a specific file/folder because the file will be
populated with information.
There are a few reasons for appending to a file:
1. There is a lot of output, so spamming the stdout/stderr is not ideal
2. If you run the same command again, after changing your `@source`
directives, you could diff the outputs. (although, the timestamps will
be different)
3. When using `DEBUG=*`, a lot of other tools also output debug
information, so writing to a file should make this better.

We also output where we are writing the file to. This looks like this
when using the CLI:
<img width="1462" alt="image"
src="https://github.com/user-attachments/assets/79c2cc95-adea-4bbd-a4f1-101de45726f5"
/>
Last but not least, this also ignores `.log` files by default
## Test plan
Ran the CLI (but you can use any tool real, since this is implemented in
Oxide) with the `DEBUG=*` flag.
The file generated, looks like the example I shared above.

Use @tailwindcss/node for import in CLI (#17502)
Closes #17501 Seems like an oversight. The CLI does have a dependency on `@tailwindcss/node` so it should use it from the public import like the other stuff. |

Improve compatibility with Safari 15 (#17435)
This PR improves the compatibility with Tailwind CSS v4 with unsupported
browsers with the goal to greatly improve compatibility with Safari 15.
To make this work, this PR makes the following changes to all code
- Change `oklab(…)` default theme values to use a percentage in the
first place (so instead of `--color-red-500: oklch(0.637 0.237 25.331);`
we now define it as `--color-red-500: oklch(63.7% 0.237 25.331);` since
this syntax has much broader support on Safari).
- Polyfill `@property` with a `@supports` query targeting older versions
of Safari and Firefox *
- Create fallbacks for the `color-mix(…)` function that use _inlined
color values from your theme_ so that they can be computed a compile
time by `lightningcss`. These fallbacks will convert to srgb to increase
compatibility.
- Create fallbacks for the _relative color_ feature used in the new
shadow utilities and using `color-mix(…)` in case _relative color_ is
applied on `currentcolor` (due to limited browser support)
- Create fallbacks for gradient interpolation methods (e.g. to support
`bg-linear-to-r/oklab`)
- Polyfill `@media` queries range syntax.
## A simplified example
Given this example CSS input:
```css
@import 'tailwindcss';
@source inline('from-cyan-500/50 bg-linear-45');
```
Here's the updated output CSS including the newly added polyfills and
updated `oklab` values:
```css
.bg-linear-45 {
--tw-gradient-position: 45deg;
background-image: linear-gradient(var(--tw-gradient-stops));
}
@supports (background-image: linear-gradient(in lab, red, red)) {
.bg-linear-45 {
--tw-gradient-position: 45deg in oklab;
}
}
.from-cyan-500\\/50 {
--tw-gradient-from: oklab(71.5% -.11682 -.08247 / .5);
--tw-gradient-stops: var(--tw-gradient-via-stops, var(--tw-gradient-position), var(--tw-gradient-from) var(--tw-gradient-from-position), var(--tw-gradient-to) var(--tw-gradient-to-position));
}
@supports (color: color-mix(in lab, red, red)) {
.from-cyan-500\\/50 {
--tw-gradient-from: color-mix(in oklab, var(--color-cyan-500) 50%, transparent);
}
}
:root, :host {
--color-cyan-500: oklch(71.5% .143 215.221);
}
@supports (((-webkit-hyphens: none)) and (not (margin-trim: 1lh))) or ((-moz-orient: inline) and (not (color: rgb(from red r g b)))) {
@layer base {
*, :before, :after, ::backdrop {
--tw-gradient-position: initial;
--tw-gradient-from: #0000;
--tw-gradient-via: #0000;
--tw-gradient-to: #0000;
--tw-gradient-stops: initial;
--tw-gradient-via-stops: initial;
--tw-gradient-from-position: 0%;
--tw-gradient-via-position: 50%;
--tw-gradient-to-position: 100%;
}
}
}
@property --tw-gradient-position {
syntax: "*";
inherits: false
}
@property --tw-gradient-from {
syntax: "<color>";
inherits: false;
initial-value: #0000;
}
@property --tw-gradient-via {
syntax: "<color>";
inherits: false;
initial-value: #0000;
}
@property --tw-gradient-to {
syntax: "<color>";
inherits: false;
initial-value: #0000;
}
@property --tw-gradient-stops {
syntax: "*";
inherits: false
}
@property --tw-gradient-via-stops {
syntax: "*";
inherits: false
}
@property --tw-gradient-from-position {
syntax: "<length-percentage>";
inherits: false;
initial-value: 0%;
}
@property --tw-gradient-via-position {
syntax: "<length-percentage>";
inherits: false;
initial-value: 50%;
}
@property --tw-gradient-to-position {
syntax: "<length-percentage>";
inherits: false;
initial-value: 100%;
}
```
## \* A note on `@property` polyfills and CSS modules
On Next.js, CSS module files are required to be _pure_, meaning that all
selectors must either be scoped to a class or an ID. Fortunatnyl for us,
this does not apply to `@property` rules which we've been using before
to initialize CSS variables.
However, since we're now bringing back the `@property` polyfills, that
would cause unexpected rules to be exported from the CSS file as this:
```css
@reference "tailwindcss";
.skew {
@apply skew-7;
}
```
Would turn to the following file:
```css
.skew {
/* … */
}
@supports (/*…*/) {
@layer base {
*, :before, :after, ::backdrop {
--tw-gradient-position: initial;
}
}
}
@property /* … */
```
Notice that this adds a `*` selector which is not considered pure.
Unfortunately there is no way for us to silence this warning or work
around it, as the dependency causing this errors
([`postcss-modules-local-by-default`](https://github.com/css-modules/postcss-modules-local-by-default))
is bundled into Next.js. To work around crashes, these polyfills will
not apply to CSS modules processed by the PostCSS extension for now.
## Testing on tailwindcss.com
To see the changes in effect, take a look at this screencast that
compares tailwindcss.com on iOS 15.5 with a version that has the patches
of this PR applied:
https://github.com/user-attachments/assets/1279d6f5-3c63-4f30-839c-198a789f4292
## Test plan
- Tested on tailwindcss.com via a preview build:
https://tailwindcss-com-git-legacy-browsers-tailwindlabs.vercel.app/
- Updated tests
- Ensure we also test on Chrome 111, Safari 16.4, Firefox 128 to
make sure we have no regressions. Also tested on Safari 16.4, 15.5, 18.0

Add @source not support (#17255)
This PR adds a new source detection feature: `@source not "…"`. It can
be used to exclude files specifically from your source configuration
without having to think about creating a rule that matches all but the
requested file:
```css
@import "tailwindcss";
@source not "../src/my-tailwind-js-plugin.js";
```
While working on this feature, we noticed that there are multiple places
with different heuristics we used to scan the file system. These are:
- Auto source detection (so the default configuration or an `@source
"./my-dir"`)
- Custom sources ( e.g. `@source "./**/*.bin"` — these contain file
extensions)
- The code to detect updates on the file system
Because of the different heuristics, we were able to construct failing
cases (e.g. when you create a new file into `my-dir` that would be
thrown out by auto-source detection, it'd would actually be scanned). We
were also leaving a lot of performance on the table as the file system
is traversed multiple times for certain problems.
To resolve these issues, we're now unifying all of these systems into
one `ignore` crate walker setup. We also implemented features like
auto-source-detection and the `not` flag as additional _gitignore_ rules
only, avoid the need for a lot of custom code needed to make decisions.
High level, this is what happens after the now:
- We collect all non-negative `@source` rules into a list of _roots_
(that is the source directory for this rule) and optional _globs_ (that
is the actual rules for files in this file). For custom sources (i.e
with a custom `glob`), we add an allowlist rule to the gitignore setup,
so that we can be sure these files are always included.
- For every negative `@source` rule, we create respective ignore rules.
- Furthermore we have a custom filter that ensures files are only read
if they have been changed since the last time they were read.
So, consider the following setup:
```css
/* packages/web/src/index.css */
@import "tailwindcss";
@source "../../lib/ui/**/*.bin";
@source not "../../lib/ui/expensive.bin";
```
This creates a git ignore file that (simplified) looks like this:
```gitignore
# Auto-source rules
*.{exe,node,bin,…}
*.{css,scss,sass,…}
{node_modules,git}/
# Custom sources can overwrite auto-source rules
!lib/ui/**/*.bin
# Negative rules
lib/ui/expensive.bin
```
We then use this information _on top of your existing `.gitignore`
setup_ to resolve files (i.e so if your `.gitignore` contains rules e.g.
`dist/` this line is going to be added _before_ any of the rules lined
out in the example above. This allows negative rules to allow-list your
`.gitignore` rules.
To implement this, we're rely on the `ignore` crate but we had to make
various changes, very specific, to it so we decided to fork the crate.
All changes are prefixed with a `// CHANGED:` block but here are the
most-important ones:
- We added a way to add custom ignore rules that _extend_ (rather than
overwrite) your existing `.gitignore` rules
- We updated the order in which files are resolved and made it so that
more-specific files can allow-list more generic ignore rules.
- We resolved various issues related to adding more than one base path
to the traversal and ensured it works consistent for Linux, macOS, and
Windows.
## Behavioral changes
1. Any custom glob defined via `@source` now wins over your `.gitignore`
file and the auto-content rules.
- Resolves #16920
3. The `node_modules` and `.git` folders as well as the `.gitignore`
file are now ignored by default (but can be overridden by an explicit
`@source` rule).
- Resolves #17318
- Resolves #15882
4. Source paths into ignored-by-default folders (like `node_modules`)
now also win over your `.gitignore` configuration and auto-content
rules.
- Resolves #16669
5. Introduced `@source not "…"` to negate any previous rules.
- Resolves #17058
6. Negative `content` rules in your legacy JavaScript configuration
(e.g. `content: ['!./src']`) now work with v4.
- Resolves #15943
7. The order of `@source` definitions matter now, because you can
technically include or negate previous rules. This is similar to your
`.gitingore` file.
9. Rebuilds in watch mode now take the `@source` configuration into
account
- Resolves #15684
## Combining with other features
Note that the `not` flag is also already compatible with [`@source
inline(…)`](https://github.com/tailwindlabs/tailwindcss/pull/17147)
added in an earlier commit:
```css
@import "tailwindcss";
@source not inline("container");
```
## Test plan
- We added a bunch of oxide unit tests to ensure that the right files
are scanned
- We updated the existing integration tests with new `@source not "…"`
specific examples and updated the existing tests to match the subtle
behavior changes
- We also added a new special tag `[ci-all]` that, when added to the
description of a PR, causes the PR to run unit and integration tests on
all operating systems.

Change Chrome target to 111 (#15389)
Resolves https://github.com/tailwindlabs/tailwindcss/discussions/15387 This PR changes the Chrome target to 111. We initially picked 120 because of the unnecessary `:dir()` down-leveling but we that was maybe a bit too recent as it was causing some necessary prefixes to not be generated (e.g. `-webkit-background-clip`). This PR changes it to 111 which we require for the `color-mix()` function. To work around the `:dir()` down-leveling we also disable the `DirSelector` lightningcss feature which is used to control this behavior: https://sourcegraph.com/github.com/parcel-bundler/lightningcss/-/blob/src/selector.rs?L1964-1965 |

Optimize generated CSS output (#14873)
This PR improves the generated CSS by running it through Lightning CSS twice.Right now Lightning CSS merges adjacent at-rules and at the end flattens the nesting. This means that after the nesting is flattened, the at-rules that are adjacent and could be merged together will not be merged. This PR improves our output by running Lightning CSS twice on the generated CSS which will make sure to merge adjacent at-rules after the nesting is flattened. Note: in the diff output you'll notice that some properties are duplicated. These need some fixes in Lightning CSS itself but they don't break anything for us right now.

Support migrating projects with multiple config files (#14863)
When migrating a project from Tailwind CSS v3 to Tailwind CSS v4, then we started the migration process in the following order: 1. Migrate the JS/TS config file 2. Migrate the source files (found via the `content` option) 3. Migrate the CSS files However, if you have a setup where you have multiple CSS root files (e.g.: `frontend` and `admin` are separated), then that typically means that you have an `@config` directive in your CSS files. These point to the Tailwind CSS config file. This PR changes the migration order to do the following: 1. Build a tree of all the CSS files 2. For each `@config` directive, migrate the JS/TS config file 3. For each JS/TS config file, migrate the source files If a CSS file does not contain any `@config` directives, then we start by filling in the `@config` directive with the default Tailwind CSS config file (if found, or the one passed in). If no default config file or passed in config file can be found, then we will error out (just like we do now) --------- Co-authored-by: Adam Wathan <adam.wathan@gmail.com> |

Auto source detection improvements (#14820)
This PR introduces a new `source(…)` argument and improves on the
existing `@source`. The goal of this PR is to make the automatic source
detection configurable, let's dig in.
By default, we will perform automatic source detection starting at the
current working directory. Auto source detection will find plain text
files (no binaries, images, ...) and will ignore git-ignored files.
If you want to start from a different directory, you can use the new
`source(…)` next to the `@import "tailwindcss/utilities"
layer(utilities) source(…)`.
E.g.:
```css
/* ./src/styles/index.css */
@import 'tailwindcss/utilities' layer(utilities) source('../../');
```
Most people won't split their source files, and will just use the simple
`@import "tailwindcss";`, because of this reason, you can use
`source(…)` on the import as well:
E.g.:
```css
/* ./src/styles/index.css */
@import 'tailwindcss' source('../../');
```
Sometimes, you want to rely on auto source detection, but also want to
look in another directory for source files. In this case, yuo can use
the `@source` directive:
```css
/* ./src/index.css */
@import 'tailwindcss';
/* Look for `blade.php` files in `../resources/views` */
@source '../resources/views/**/*.blade.php';
```
However, you don't need to specify the extension, instead you can just
point the directory and all the same automatic source detection rules
will apply.
```css
/* ./src/index.css */
@import 'tailwindcss';
@source '../resources/views';
```
If, for whatever reason, you want to disable the default source
detection feature entirely, and only want to rely on very specific glob
patterns you define, then you can disable it via `source(none)`.
```css
/* Completely disable the default auto source detection */
@import 'tailwindcss' source(none);
/* Only look at .blade.php files, nothing else */
@source "../resources/views/**/*.blade.php";
```
Note: even with `source(none)`, if your `@source` points to a directory,
then auto source detection will still be performed in that directory. If
you don't want that, then you can simply add explicit files in the globs
as seen in the previous example.
```css
/* Completely disable the default auto source detection */
@import 'tailwindcss' source(none);
/* Run auto source detection in `../resources/views` */
@source "../resources/views";
```

Improve @tailwindcss/postcss performance for initial builds (#14565)
This PR improves the performance of the `@tailwindcss/postcss` plugin. Before this change we created 2 compiler instances instead of a single one. On a project where a `tailwindcss.config.ts` file is used, this means that the timings look like this: ``` [@tailwindcss/postcss] Setup compiler: 137.525ms ⋮ [@tailwindcss/postcss] Setup compiler: 43.95ms ``` This means that with this small change, we can easily shave of ~50ms for initial PostCSS builds. --------- Co-authored-by: Philipp Spiess <hello@philippspiess.com> Co-authored-by: Jordan Pittman <jordan@cryptica.me> |

Expose timing information in debug mode (#14553)
This PR exposes when using the the `DEBUG` environment variable. This follows the `DEBUG` conventions where: - `DEBUG=1` - `DEBUG=true` - `DEBUG=*` - `DEBUG=tailwindcss` Will enable the debug information, but when using: - `DEBUG=0` - `DEBUG=false` - `DEBUG=-tailwindcss` It will not. This currently only exposes some timings related to: 1. Scanning for candidates 2. Building the CSS 3. Optimizing the CSS We can implement a more advanced version of this where we also expose more fine grained information such as the files we scanned, the amount of candidates we found and so on. But I believe that this will be enough to start triaging performance related issues. |

CLI: Use the right base when loading files from stdin (#14522)
Fixes #14521 When using the CLI to read files from `stdin` like this: ```bash npx tailwindcss --input=- -o bar.css < foo.css ``` We need to set the `base` path to be the current working directory (`process.cwd()`). However, `cwd()` already _is_ a directory and calling `dirname()` on it did go to the parent directory _which might not have the `tailwindcss` dependency installed. |

Resolve @import in core (#14446)
This PR brings `@import` resolution into Tailwind CSS core. This means that our clients (PostCSS, Vite, and CLI) no longer need to depend on `postcss` and `postcss-import` to resolve `@import`. Furthermore this simplifies the handling of relative paths for `@source`, `@plugin`, or `@config` in transitive CSS files (where the relative root should always be relative to the CSS file that contains the directive). This PR also fixes a plugin resolution bug where non-relative imports (e.g. directly importing node modules like `@plugin '@tailwindcss/typography';`) would not work in CSS files that are based in a different npm package. ### Resolving `@import` The core of the `@import` resolution is inside `packages/tailwindcss/src/at-import.ts`. There, to keep things performant, we do a two-step process to resolve imports. Imagine the following input CSS file: ```css @import "tailwindcss/theme.css"; @import "tailwindcss/utilities.css"; ``` Since our AST walks are synchronous, we will do a first traversal where we start a loading request for each `@import` directive. Once all loads are started, we will await the promise and do a second walk where we actually replace the AST nodes with their resolved stylesheets. All of this is recursive, so that `@import`-ed files can again `@import` other files. The core `@import` resolver also includes extensive test cases for [various combinations of media query and supports conditionals as well als layered imports](https://developer.mozilla.org/en-US/docs/Web/CSS/@import). When the same file is imported multiple times, the AST nodes are duplicated but duplicate I/O is avoided on a per-file basis, so this will only load one file, but include the `@theme` rules twice: ```css @import "tailwindcss/theme.css"; @import "tailwindcss/theme.css"; ``` ### Adding a new `context` node to the AST One limitation we had when working with the `postcss-import` plugin was the need to do an additional traversal to rewrite relative `@source`, `@plugin`, and `@config` directives. This was needed because we want these paths to be relative to the CSS file that defines the directive but when flattening a CSS file, this information is no longer part of the stringifed CSS representation. We worked around this by rewriting the content of these directives to be relative to the input CSS file, which resulted in added complexity and caused a lot of issues with Windows paths in the beginning. Now that we are doing the `@import` resolution in core, we can use a different data structure to persist this information. This PR adds a new `context` node so that we can store arbitrary context like this inside the Ast directly. This allows us to share information with the sub tree _while doing the Ast walk_. Here's an example of how the new `context` node can be used to share information with subtrees: ```ts const ast = [ rule('.foo', [decl('color', 'red')]), context({ value: 'a' }, [ rule('.bar', [ decl('color', 'blue'), context({ value: 'b' }, [ rule('.baz', [decl('color', 'green')]), ]), ]), ]), ] walk(ast, (node, { context }) => { if (node.kind !== 'declaration') return switch (node.value) { case 'red': assert(context.value === undefined) case 'blue': assert(context.value === 'a') case 'green': assert(context.value === 'b') } }) ``` In core, we use this new Ast node specifically to persist the `base` path of the current CSS file. We put the input CSS file `base` at the root of the Ast and then overwrite the `base` on every `@import` substitution. ### Removing the dependency on `postcss-import` Now that we support `@import` resolution in core, our clients no longer need a dependency on `postcss-import`. Furthermore, most dependencies also don't need to know about `postcss` at all anymore (except the PostCSS client, of course!). This also means that our workaround for rewriting `@source`, the `postcss-fix-relative-paths` plugin, can now go away as a shared dependency between all of our clients. Note that we still have it for the PostCSS plugin only, where it's possible that users already have `postcss-import` running _before_ the `@tailwindcss/postcss` plugin. Here's an example of the changes to the dependencies for our Vite client ✨ : <img width="854" alt="Screenshot 2024-09-19 at 16 59 45" src="https://github.com/user-attachments/assets/ae1f9d5f-d93a-4de9-9244-61af3aff1237"> ### Performance Since our Vite and CLI clients now no longer need to use `postcss` at all, we have also measured a significant improvement to the initial build times. For a small test setup that contains only a hand full of files (nothing super-complex), we measured an improvement in the **3.5x** range: <img width="1334" alt="Screenshot 2024-09-19 at 14 52 49" src="https://github.com/user-attachments/assets/06071fb0-7f2a-4de6-8ec8-f202d2cc78e5"> The code for this is in the commit history if you want to reproduce the results. The test was based on the Vite client. ### Caveats One thing to note is that we previously relied on finding specific symbols in the input CSS to _bail out of Tailwind processing completely_. E.g. if a file does not contain a `@tailwind` or `@apply` directive, it can never be a Tailwind file. Since we no longer have a string representation of the flattened CSS file, we can no longer do this check. However, the current implementation was already inconsistent with differences on the allowed symbol list between our clients. Ideally, Tailwind CSS should figure out wether a CSS file is a Tailwind CSS file. This, however, is left as an improvement for a future API since it goes hand-in-hand with our planned API changes for the core `tailwindcss` package. --------- Co-authored-by: Jordan Pittman <jordan@cryptica.me> |

Improve the CLI output when nothing changed (#14351)
When we observe that no new candidates were found, then we can return early because nothing really changed. There is also no need to re-optimize (use Lightning CSS) in this case. But this had a side effect that when no new candidates were detected, that you didn't see any output either. This feels like nothing is working from a DX perspective. Typically you are changing things, so it's not really a problem. But the moment you use a class that already existed (e.g.: in another file) you also don't get any output because we have a shared cache. This PR solves that by always showing the output. But it still doesn't write to disk if nothing changed. --------- Co-authored-by: Adam Wathan <adam.wathan@gmail.com> |

Support loading config files via @config (#14239)
In Tailwind v4 the CSS file is the main entry point to your project and is generally configured via `@theme`. However, given that all v3 projects were configured via a `tailwind.config.js` file we definitely need to support those. This PR adds support for loading existing Tailwind config files by adding an `@config` directive to the CSS — similar to how v3 supported multiple config files except that this is now _required_ to use a config file. You can load a config file like so: ``` @import "tailwindcss"; @config "./path/to/tailwind.config.js"; ``` A few notes: - Both CommonJS and ESM config files are supported (loaded directly via `import()` in Node) - This is not yet supported in Intellisense or Prettier — should hopefully land next week - TypeScript is **not yet** supported in the config file — this will be handled in a future PR. --------- Co-authored-by: Philipp Spiess <hello@philippspiess.com> Co-authored-by: Adam Wathan <adam.wathan@gmail.com> Co-authored-by: Robin Malfait <malfait.robin@gmail.com> |

Add standalone CLI (#14270)
This PR adds a new standalone client: A single-binary file that you can
use to run Tailwind v4 without having a node setup. To make this work we
use Bun's single-binary build which can properly package up native
modules and the bun runtime for us so we do not have to rely on any
expand-into-tmp-folder-at-runtime workarounds.
When running locally, `pnpm build` will now standalone artifacts inside
`packages/@tailwindcss-standalone/dist`. Note that since we do not build
Oxide for other environments in the local setup, you won't be able to
use the standalone artifacts for other platforms in local dev mode.
Unfortunately Bun does not have support for Windows ARM builds yet but
we found that using the `bun-baseline` runtime for Windows x64 would
make the builds work fine in ARM emulation mode:
Some Bun related issues we faced and worked around:
- We found that the regular Windows x64 build of `bun` does not run on
Windows ARM via emulation. Instead, we have to use the `bun-baseline`
builds which emulate correctly.
- When we tried to bundle artifacts with [embed
directories](https://bun.sh/docs/bundler/executables#embed-directories),
node binary dependencies were no longer resolved correctly even though
they would still be bundled and accessible within the [`embeddedFiles`
list](https://bun.sh/docs/bundler/executables#listing-embedded-files).
We worked around this by using the `import * as from ... with { type:
"file" };` and patching the resolver we use in our CLI.
- If you have an import to a module that is used as a regular import
_and_ a `with { type: "file" }`, it will either return the module in
both cases _or_ the file path when we would expect only the `with {
type: "file" }` import to return the path. We do read the Tailwind CSS
version via the file system and `require.resolve()` in the CLI and via
`import * from './package.json'` in core and had to work around this by
patching the version resolution in our CLI.
```ts
import packageJson from "./package.json"
import packageJsonPath from "./package.json" with {type: "file"}
// We do not expect these to be equal
packageJson === packageJsonPath
```
- We can not customize the app icon used for Windows `.exe` builds
without decompiling the binary. For now we will leave the default but
one workaround is to [use tools like

Improve Oxide scanner API (#14187)
This PR updates the API for interacting with the Oxide API. Until now,
we used the name `scanDir(…)` which is fine, but we do way more work
right now.
We now have features such as:
1. Auto source detection (can be turned off, e.g.: `@tailwindcss/vite`
doesn't need it)
2. Scan based on `@source`s found in CSS files
3. Do "incremental" rebuilds (which means that the `scanDir(…)` result
was stateful).
To solve these issues, this PR introduces a new `Scanner` class where
you can pass in the `detectSources` and `sources` options. E.g.:
```ts
let scanner = new Scanner({
// Optional, omitting `detectSources` field disables automatic source detection
detectSources: { base: __dirname },
// List of glob entries to scan. These come from `@source` directives in CSS.
sources: [
{ base: __dirname, pattern: "src/**/*.css" },
// …
],
});
```
The scanner object has the following API:
```ts
export interface ChangedContent {
/** File path to the changed file */
file?: string
/** Contents of the changed file */
content?: string
/** File extension */
extension: string
}
export interface DetectSources {
/** Base path to start scanning from */
base: string
}
export interface GlobEntry {
/** Base path of the glob */
base: string
/** Glob pattern */
pattern: string
}
export interface ScannerOptions {
/** Automatically detect sources in the base path */
detectSources?: DetectSources
/** Glob sources */
sources?: Array<GlobEntry>
}
export declare class Scanner {
constructor(opts: ScannerOptions)
scan(): Array<string>
scanFiles(input: Array<ChangedContent>): Array<string>
get files(): Array<string>
get globs(): Array<GlobEntry>
}
```
The `scanFiles(…)` method is used for incremental rebuilds. It takes the
`ChangedContent` array for all the new/changes files. It returns whether
we scanned any new candidates or not.
Note that the `scanner` object is stateful, this means that we don't
have to track candidates in a `Set` anymore. We can just call
`getCandidates()` when we need it.
This PR also removed some unused code that we had in the `scanDir(…)`
function to allow for sequential or parallel `IO`, and sequential or
parallel `Parsing`. We only used the same `IO` and `Parsing` strategies
for all files, so I just got rid of it.

Use import to load plugins (#14132)
Alternative to #14110 This PR changes the way how we load plugins to be compatible with ES6 async `import`s. This allows us to load plugins even inside the browser but it comes at a downside: We now have to change the `compile` API to return a `Promise`... So most of this PR is rewriting all of the call sites of `compile` to expect a promise instead of the object. --------- Co-authored-by: Jordan Pittman <jordan@cryptica.me> |

Add @source support (#14078)
This PR is an umbrella PR where we will add support for the new `@source` directive. This will allow you to add explicit content glob patterns if you want to look for Tailwind classes in other files that are not automatically detected yet. Right now this is an addition to the existing auto content detection that is automatically enabled in the `@tailwindcss/postcss` and `@tailwindcss/cli` packages. The `@tailwindcss/vite` package doesn't use the auto content detection, but uses the module graph instead. From an API perspective there is not a lot going on. There are only a few things that you have to know when using the `@source` directive, and you probably already know the rules: 1. You can use multiple `@source` directives if you want. 2. The `@source` accepts a glob pattern so that you can match multiple files at once 3. The pattern is relative to the current file you are in 4. The pattern includes all files it is matching, even git ignored files 1. The motivation for this is so that you can explicitly point to a `node_modules` folder if you want to look at `node_modules` for whatever reason. 6. Right now we don't support negative globs (starting with a `!`) yet, that will be available in the near future. Usage example: ```css /* ./src/input.css */ @import "tailwindcss"; @source "../laravel/resources/views/**/*.blade.php"; @source "../../packages/monorepo-package/**/*.js"; ``` It looks like the PR introduced a lot of changes, but this is a side effect of all the other plumbing work we had to do to make this work. For example: 1. We added dedicated integration tests that run on Linux and Windows in CI (just to make sure that all the `path` logic is correct) 2. We Have to make sure that the glob patterns are always correct even if you are using `@import` in your CSS and use `@source` in an imported file. This is because we receive the flattened CSS contents where all `@import`s are inlined. 3. We have to make sure that we also listen for changes in the files that match any of these patterns and trigger a rebuild.

Add Windows CI (#14065)
This PR changes the GitHub action workflow for V4 to start running all unit tests and build on both Ubuntu (our current default) _and_ Windows. This is to ensure we catch issues with paths and other Windows-specific things sooner. It does, however, not replace testing on Windows. |

Improve incremental builds (#13168)
* ensure we don't crash on deleted files * change return type of `compile` to include a `rebuild()` function This will allow us in the future to perform incremental rebuilds after the initial rebuild. This is purely the API change so that we can prepare all the call sites to use this new API. * set `@tailwind utilities` nodes Instead of replacing the node that represents the `@tailwind utilities` with the generated AST nodes from the rawCandidates, we will set the nodes of the `@tailwind utilities` rule to the AST nodes instead. This way we dont' have to remove and replace the `@tailwind utilities` rule with `n` new nodes. This will later allow us to track the `@tailwindcss utilities` rule itself and update its `nodes` for incremental rebuilds. This also requires a small change to the printer where we now need to print the children of the `@tailwind utilities` rule. Note: we keep the same `depth` as-if the `@tailwindcss utilities` rule was not there. Otherwise additional indentation would be present. * move sorting to the `ast.sort()` call This will allow us to keep sorting AST nodes in a single spot. * move parser functions to the `DesignSystem` This allows us to put all the parsers in the `DesignSystem`, this allows us to scope the parsers to the current design system (the current theme, current utility values and variants). The implementation of these parsers are also using a `DefaultMap` implementation. This allows us to make use of caching and only parse a candidate, parse a variant or compile AST nodes for a given raw candidate once if we've already done this work in the past. Again, this is scoped to the `DesignSystem` itself. This means that if the corresponding theme changes, then we will create a new `DesignSystem` entirely and the caches will be garbage collected. This is important because a candidate like `bg-primary` can be invalid in `DesignSystem` A, but can be valid in `DesignSystem` B and vice versa. * ensure we sort variants alphabetically by root For incremental rebuilds we don't know all the used variants upfront, which means that we can't sort them upfront either (what we used to do). This code now allows us to sort the variants deterministically when sorting the variants themselves instead of relying on the fact that they used to be sorted before. The sort itself could change slightly compared to the previous implementation (especially when you used stacked variants in your candidates), but it will still be deterministic. * replace `localeCompare` comparisons Use cheaper comparisons than `localeCompare` when comparing 2 strings. We currently don't care if it is 100% correctly sorted, but we just want consistent sorting. This is currently faster compared to `localeCompare`. Another benefit is that `localeCompare` could result in non-deterministic results if the CSS was generated on 2 separate computers where the `locale` is different. We could solve that by adding a dedicated locale, but it would still be slower compared to this. * track invalid candidates When an incoming raw candidates doesn't produce any output, then we can mark it as an invalid candidate. This will allow us to reduce the amount of candidates to handle in incremental rebuilds. * add initial incremental rebuild implementation This includes a number of steps: 1. Track the `@tailwind utilities` rule, so that we can adjust its nodes later without re-parsing the full incoming CSS. 2. Add the new incoming raw candidates to the existing set of candidates. 3. Parse the merged set to `compileCandidates` (this can accept any `Iterable<string>`, which means `string[]`, `Set<string>`, ...) 4. Get the new AST nodes, update the `@tailwind utilities` rule's nodes and re-print the AST to CSS. * improvement 1: ignore known invalid candidates This will reduce the amount of candidates to handle. They would eventually be skipped anyway, but now we don't even have to re-parse (and hit a cache) at all. * improvement 2: skip work, when generated AST is the same Currently incremental rebuilds are additive, which means that we are not keeping track if we should remove CSS again in development. We can exploit this information, because now we can quickly check the amoutn of generated AST nodes. - If they are the same then nothing new is generated — this means that we can re-use the previous compiled CSS. We don't even have to re-print the AST because we already did do that work in the past. - If there are more AST nodes, something new is generated — this means that we should update the `@tailwind utilities` rule and re-print the CSS. We can store the result for future incremental rebuilds. * improvement 3: skip work if no new candidates are detected - We already know a set of candidates from previous runs. - We also already know a set of candidates that are invalid and don't produce anything. This means that an incremental rebuild could give us a new set of candidates that either already exist or are invalid. If nothing changes, then we can re-use the compiled CSS. This actually happens more often than you think, and the bigger your project is the better this optimization will be. For example: ``` // Imagine file A exists: <div class="flex items-center justify-center"></div> <button class="text-red-500">Delete</button> ``` ``` // Now you add a second file B: <div class="text-red-500 flex"></div> ``` You just created a brand new file with a bunch of HTML elements and classes, yet all of the candidates in file B already exist in file A, so nothing changes to the actual generated CSS. Now imagine the other hundreds of files that already contain hundreds of classes. The beauty of this optimization is two-fold: - On small projects, compiling is very fast even without this check. This means it is performant. - On bigger projects, we will be able to re-use existing candidates. This means it stays performant. * remove `getAstNodeSize` We can move this up the tree and move it to the `rebuild` function instead. * remove invalid candidate tracking from `DesignSystem` This isn't used anywhere but only in the `rebuild` of the compile step. This allows us to remove it entirely from core logic, and move it up the chain where it is needed. * replace `throwOnInvalidCandidate` with `onInvalidCanidate` This was only needed for working with `@apply`, now this logic _only_ exists in the code path where we are handling `@apply`. * update `compile` API signature * update callsite of `compile()` function * fix typo |

[v4] Make CSS optimization and minification configurable (#13130)
* only run Lightning CSS when passing `--minify` to the CLI
* only optimize the CSS when creating a production build
* add `optimize` option to PostCSS plugin
- The optimize option can be set to `true`, which will optimize
(unnesting, adding browser prefixes, lowering values) and minify
- The optimize option can also be set to `{ minify: false }`, which will
optimize but not minify.
* default `optimize` option to the true for `NODE_ENV=production`
* add `--optimize` flag to CLI
This will only optimize the CSS output without minification.
* update `--minify` description
* update changelog
