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.
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.
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: "*";

}
@property --tw-gradient-from {
syntax: "<color>";
inherits: false;
initial-value: #0000;
}

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
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.
[ci-all]

Prepare the 4.0.16 release.
~~Also added a commit to mark the `--value('…')` and `--modifier('…')`
with literals strings as an experimental feature (aka not shipped in
this PR). But we can revert that commit if we still want to ship it in
4.0.16 instead of 4.1.~~

This PR fixes an issue where installing a specific version of
`@tailwindcss/postcss` and `tailwindcss` could still result in a version
mismatch. This is because we were relying on `^4.0.6` for example
instead of `4.0.6`.
This PR now pins all these versions to prevent this:
```
❯ pnpm why tailwindcss
devDependencies:
@tailwindcss/postcss 4.0.5
├─┬ @tailwindcss/node 4.0.6
│ └── tailwindcss 4.0.6
└── tailwindcss 4.0.5
```

This PR upgrades `lightningcss` to `1.29.0` and uses the [new feature
flag](304389600f)
to disable the light-dark function transpilation.
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
Closes#15160
We need to set browser targets for each browser individually to see
vendor prefixes created for each browser.
Exact values are up for discussion, this first pass is taken from
@adamwathan's comments in

Fix#15085
We were relying on Node's printing of errors during build but this
prints the line of code the error occurs on. Since the code is minified
you'd get a really long string of code that wrapped a ton in the console
before the actual error. Now we print errors during build like we do in
watch mode.
