Show suggestions for known matchVariant values (#18798)
Given this variant:
```js
matchVariant(
  "foo",
  (value) => `&:is([data-foo='${value}'])`,
  {
    values: {
      DEFAULT: "",
      bar: "bar",
      baz: "bar",
    },
  }
)
```

We weren't listing `foo-bar` and `foo-baz` in IntelliSense. This PR
fixes that.

Discard matchVariant matches with unknown named values (#18799)
This PR fixes two issues:
- When a variant is defined by `matchVariant` it could match unknown
values but not apply the variant (because it's unknown). This would
result in a utility being output that is the _same_ as a bare utility
without variants but a longer name. These were intended to be discarded
but weren't done so correctly.
- Similarly, when we encounter a known value but its not a string the
same thing would happen where we'd output a utility without applying the
variant. This was also intended to be discarded.

Basically given this code:
```js
matchVariant(
  "foo",
  (value) => `&:is([data-foo='${value}'])`,
  {
    values: {
      DEFAULT: "",
      bar: "bar",
      obj: { some: "object" },
    },
  }
)
```

And this HTML:
```html
<div class="foo-bar:bg-none foo-[baz]:bg-none foo-baz:bg-none foo-obj:bg-none"></div>
```

This CSS would be produced:
```css
@layer utilities {
  .foo-bar\:bg-none {
    &:is([data-foo='bar']) {
      background-image: none;
    }
  }
  /* this one shouldn't be here */
  .foo-baz\:bg-none {
    background-image: none;
  }
  /* this one shouldn't be here */
  .foo-obj\:bg-none {
    background-image: none;
  }
  .foo-\[baz\]\:bg-none {
    &:is([data-foo='baz']) {
      background-image: none;
    }
  }
}
```

Don't transition visibility when using transition (#18795)
We introduced an accidental breaking change a few months ago in 4.1.5
with #17812.

We added `visibility` to the property list in `transition` which
unfortunately only applies its change instantly when going from
invisible -> visible.

I've checked `display`, `content-visibility`, and `pointer-events` and
they apply their change instantly (as best I can tell) when
transitioning by default. And `overlay` only "applies" for discrete
transitions so it can stay as well.

The spec has this to say about [animating
`visibility`](https://www.w3.org/TR/web-animations-1/#animating-visibility):
> For the visibility property, visible is interpolated as a discrete
step where values of p between 0 and 1 map to visible and other values
of p map to the closer endpoint; if neither value is visible then
discrete animation is used.

This means that for visible (t=0) -> hidden (t=1) the timeline looks
like this:
- t=0.0: visible
- t=0.5: visible
- t=0.999…8: visible
- t=1.0: invisible

This means that for invisible (t=0) -> visible (t=1) the timeline looks
like this:
- t=0.0: invisible
- t=0.000…1: visible
- t=0.5: visible
- t=1.0: visible

So the value *is* instantly applied if the element is initially
invisible but when going the other direction this is not the case. This
happens whether or not the transition type is discrete.

While the spec calls out [`display` as working
similarly](https://drafts.csswg.org/css-display-4/#display-animation) in
practice this is only the case when `transition-behavior` is explicitly
set to `allow-discrete` otherwise the change is instant for both
directions.

Add --border-color to divide theme keys (#18704)
## Summary

In Tailwind 3 the border colors were able to be used with `divide`
utilities. I made it so that's true for Tailwind 4.

## Test plan

Just used `pnpm run tdd` and making it fails then making sure it passes.

Fix false-positive migrations in addEventListener and JavaScript variable names (#18718)
This PR fixes 2 false-positives when running the upgrade tool on a
Tailwind CSS v3 project converting it to a Tailwind CSS v4 project.

The issue occurs around migrations with short simple names that have a
meaning outside if Tailwind CSS, e.g. `blur` and `outline`.

This PR fixes 2 such cases:


1. The `addEventListener` case:

   ```js
   document.addEventListener('blur', handleBlur)
   ```

We do this by special casing the `addEventListener(` case and making
sure the first argument to `addEventListener` is never migrated.

2. A JavaScript variable with default value:

   ```js
   function foo({ foo = "bar", outline = true, baz = "qux" }) {
     // ...
   }
   ```

The bug is relatively subtle here, but it has actually nothing to do
with `outline` itself, but rather the fact that some quote character
came before and after it on the same line...

One of our heuristics for determining if a migration on these small
words is safe, is to ensure that the candidate is inside of a string.
Since we didn't do any kind of quote balancing, we would consider the
`outline` to be inside of a string, even though it is not.

So to actually solve this, we do some form of quote balancing to ensure
that it's _not_ inside of a string in this case.

Additionally, this PR also introduces a small refactor to the
`is-safe-migration.test.ts` file where we now use a `test.each` to
ensure that failing tests in the middle don't prevent the rest of the
tests from running.

### Test plan

1. Added dedicated tests for the cases mentioned in the issue (#18675).
2. Added a few more tests with various forms of whitespace.

Suggest bare values for flex-* utilities (#18642)
Fixes
https://github.com/tailwindlabs/tailwindcss-intellisense/issues/1426

We weren't suggesting things like `flex-1`. This adds that. I'm not sure
if we want to suggest more `flex-<number>` values though. I've added
1–12 but am open to changing this.

Allow users to disable url rewriting in the PostCSS plugin (#18321)
Since we (optionally) support source maps now it's possible that a later
PostCSS plugin that *still* does url rewriting might fail to do so
correctly because nodes will have preserved source locations in dev
builds where before we "pretended" that everything came from the
original file.

But, because we can't know if such a plugin is present, disabling this
behavior when source maps are enabled could cause issues *and* would be
a breaking change.

I wish everything *could just work* here but realistically we can't know
what plugins have run before our PostCSS plugin or what plugins will run
after so the best option (I think) we can offer here is to allow users
to disable url rewriting at the plugin level.

Fixes #16700

Don’t output CSS objects with false or undefined in the AST (#18571)
Fixes https://github.com/tailwindlabs/tailwindcss-typography/issues/384

Basically when addUtilities/addComponents/matchUtilities/matchComponents
saw a value of `false` it was being output instead of being discarded
like it was in v3.

The types really require these to be strings but for things like the
typography plugin this isn't really carried through from its theme
config so it was easy to put anything in there and not realize it
doesn't match the expected types.

Basically this:
```js
addUtilities({
  '.foo': {
    a: 'red',
    'z-index': 0,
    '.bar': false,
    '.baz': null, // this one already worked
    '.qux': undefined,
  },

Now works like it did in v3 and omits `.bar`, `.baz`, and `.qux`

Center the dropdown icon added to an input with a paired datalist in Chrome (#18511)
This PR tweaks the dropdown arrow added to an input by Chrome when it
has a `list` attribute pointing to a `<datalist>`.

Right now the arrow isn't centered vertically:

<img width="227" height="58" alt="Screenshot 2025-07-14 at 15 41 50"
src="https://github.com/user-attachments/assets/b354a5e8-432d-432d-bfe4-f7b6f6683548"
/>

The cause of this is the line height being inherited into the pseudo
element which controls how the marker is positioned. I *think* this is
because it's being drawn with unicode symbols but I'm not sure. It could
just be from the `list-item` display.

After this PR changes the line height its centered again:

<img width="227" height="58" alt="Screenshot 2025-07-14 at 15 42 05"
src="https://github.com/user-attachments/assets/1afa1f33-cc28-4b1f-9e04-e546f6848f57"
/>

Some notes:

This only affects Chrome and also does not appear to cause issues for
date/time inputs. While weird that this pseudo is the one used for a
`<datalist>` marker it is indeed correct.

Fixes #18499

Can use this Play to test the change:

Track source locations through @plugin and @config (#18329)
Fixes https://github.com/tailwindlabs/tailwindcss-forms/issues/182

Inside JS plugins and configs we weren't tracking source location info
so using things like `addBase(…)` could result in warnings inside Vite's
url rewriting PostCSS plugin because not all declarations had a source
location.

The goal here is for calls to `addBase` to generate CSS that points back
to the `@plugin` or `@config` that resulted in it being called.

Don't consider the global important state in @apply (#18404)
Fixes #18400

In v3 when you used `important: true` it did not affect `@apply`.
However, in v4 it does and there's no way to make it *not*. This is
definitely a bug and would be unexpected for users coming from v3 who
use `@apply` and `important` together.

Basically, the following code, along with the detected utility `flex` in
source files…

```css
@import 'tailwindcss/utilities' important;
.flex-explicitly-important {
  @apply flex!;
}
.flex-not-important {
  @apply flex;
}
```

… would output this:
```css
.flex {
  display: flex !important;
}
.flex-explicitly-important  {
  display: flex !important;
}
.flex-not-important {
  display: flex !important;
}
```

But it's expected that `@apply` doesn't consider the "global" important
state. This PR addresss this problem and now the output is this:

```css
.flex {
  display: flex !important;
}
.flex-explicitly-important  {
  display: flex !important;
}
.flex-not-important {
  display: flex; /* this line changed */
}
```

If you want to mark a utility as important in `@apply` you can still use
`!` after the utility to do so as shown above.

feat: add Vite 7 support to the @tailwindcss/vite plugin (#18384)
Closes #18381 

* [Changelog for Vite 7.0.0
(2025-06-24)](https://github.com/vitejs/vite/blob/main/packages/vite/CHANGELOG.md#700-2025-06-24)

Starting from Vite 7, Node 18 support will be dropped, which doesn't
really affect Tailwind. It might be worth mentioning in the
documentation that the recommended minimum Node versions are 20.19 and
22.12.

Vite 7 is only available in ESM format, which is also not an issue.

Vite's browser support aligns with the v4 guidelines:
```
Chrome 87 → 107       (tw: 111)
Edge 88 → 107         (tw: 111)
Firefox 78 → 104      (tw: 128)
Safari 14.0 → 16.0    (tw: 16.4)
```
* [Vite 7 - Browser
Support](https://vite.dev/guide/migration.html#default-browser-target-change)
* [Tailwind CSS v4 - Browser
Support](https://tailwindcss.com/docs/compatibility#browser-support)

So, at first glance, there's nothing more to do except enabling support
for these versions.

Fix missing space around - when using % regression (#18289)
This PR fixes a regression we shipped in v4.1.9, when using arbitrary
values and injecting spaces around operator.

When you use `w-[calc(100%-var(--foo))]`, you expect that this generates
valid CSS:

```css
width: calc(100% - var(--foo));
```

But due to a regression, we generated:

```css
width: calc(100%-var(--foo));
```

Which is invalid CSS.

This is because the algorithm we used to know when we had to inject a
space around the `-` didn't take the `%` sign into account.

We also didn't handle uppercase units like `123PX` properly. This PR
fixes both issues.

## Test plan

1. Added a regression test for the `%`
2. Added a regression test for uppercase units like `123PX`

Fixes: #18288

fix: don't break CSS keywords when formatting math expressions (#18220)
Fixes #18219

## Summary

In an arbitrary value, if there's a non-numeric character both before
and after a hyphen, there's no need for a space.

## Test plan

`decodeArbitraryValue` will correctly format special CSS values like
`fit-content`. I believe spaces are only necessary if there's a digit
either before or after the hyphen.

```js
decodeArbitraryValue('min(fit-content,calc(100dvh-4rem))')
```

This way, the result of the following arbitrary value will also be
correct:

```html
<div class="min-h-[min(fit-content,calc(100dvh-4rem))]"></div>
```

CSS Parser: Handle string with semi-colon in custom properties. (#18251)
Strings are not parsed correctly for custom properties which makes the
following CSS raise an `Unterminated string: ";"` error:

```css
:root { 
  --custom: 'data:text/plain;base64,SGVsbG8sIFdvcmxkIQ==';
}
```

According to the spec, we should accept semi-colon as long as they are
not at the top level.
> The allowed syntax for [custom
properties](https://drafts.csswg.org/css-variables/#custom-property) is
extremely permissive. The <declaration-value> production matches any
sequence of one or more tokens, so long as the sequence does not contain
bad-string-token, bad-url-token, unmatched )-token, ]-token, or }-token,
or top-level semicolon-token tokens or delim-token tokens with a value
of "!".

Extract from: https://drafts.csswg.org/css-variables/#syntax

I was only able to reproduce with **tailwindcss v4**, the previous
version seems to support this. This issue is mitigated by the fact that
even if you want to use a data URL in a custom property, you would need
to wrap the value in a `url()` anyway:

```css
:root { 
  --my-icon-url: url('data:image/svg+xml;base64,...==');
}

.icon {
  background-image: var(--my-icon-url);
}
```

Which works perfectly fine with the current/latest version (v4.1.8).

The fix suggested is to share the same code between regular property and
custom property when it comes to detect that the value is a string
starting with a `SINGLE_QUOTE` or `DOUBLE_QUOTE`. I have moved the
existing code in a `findEndStringIdx` which returns the position of the
ending single/double quote.

Do not migrate blur in wire:model.blur (#18216)
This PR fixes an issue where the `blur` in `wire:model.blur="…"` was
incorrectly migrated. We solved it by marking `wire:…` as an unsafe
region (`…` can be anything but whitespace).

Fixes: #18187

## Test plan

Added a test with this use case

Migrate negative arbitrary values to negative bare values (#18212)
This PR adds some improvements to the upgrade tool where it can now also
migrate negative arbitrary values to negative bare values.

We already had support for the positive version of this:
```diff
- mb-[32rem]
+ mb-128
```

But now it can also handle negative values:
```diff
- mb-[-32rem]
+ -mb-128
```

The only tricky part here is that we had to hoist the `-` sign. Before
this PR, we were actually generating `mb--128` and that is invalid so it
was thrown out.

## Test plan

1. Added a test to ensure that the negative values are correctly
transformed.

Improve upgrade migrations (#18184)
This PR fixes 2 issues with the migration tool where certain classes
weren't migrated. This PR fixes those 2 scenarios:

### Scenario 1

When you have an arbitrary opacity modifier that doesn't use `%`, but is
just a number typically between `0` and `1` then this was not converted
to the bare value equivalent before.

E.g.:

```html
<div class="bg-[#f00]/[0.16]"></dv>
```

Will now be converted to:

```html
<div class="bg-[#f00]/16"></dv>
```

### Scenario 2

Fixes a bug when a CSS function was used in a fallback value in the CSS
variable shorthand syntax. In that case we didn't migrate the class to
the new syntax.

This was because we assumed that a `(` was found, that we are dealing
with a CSS function.

E.g.: 
```html
<div class="w-[--spacing(1)]"></div>
                        ^  This indicates a CSS function, we should not be 
                           converting this to `w-(--spacing(1))`
```

But if a function was used as a fallback value, for example:

```html
<div class="bg-[--my-color,theme(colors.red.500)]"></dv>
```

Then we also didn't migrate it, but since the function call is in the
fallback, we can still migrate it.

Will now properly be converted to:

```html
<div class="bg-(--my-color,var(--color-red-500))"></dv>
```


## Test plan

1. Added a test for the first case
2. Added a test for the second case
3. Also added an integration-like test that runs all the migration steps
to make sure that the `theme(…)` in the fallback also gets updated to
`var(…)`. This one caught an issue because the `var(…)` wasn't handling
prefixes correctly.

Improve error messages when @apply fails (#18059)
This PR improves error messages when `@apply` fails. Right now it gives
you a generic error message that you cannot apply a certain utility.

```css
.foo {
  @apply bg-red-500;
}
```

Would result in:
```
Cannot apply unknown utility class: bg-red-500
```

However, there are some situations where we can give you more context
about what's happening.

### Missing `@import "tailwindcss"` or `@reference`

If you are in a Vue file for example, and you have the following code:
```vue
<template>
  <div class="foo"></div>
</template>

<style>
.foo {
  @apply bg-red-500;
}
</style>
```

Then this will now result in:
```
Cannot apply unknown utility class `bg-white`. Are you using CSS modules or similar and missing `@reference`? https://tailwindcss.com/docs/functions-and-directives#reference-directive
```

We do this by checking if we found a `@tailwind utilities` or
`@reference`. If not, we throw this more specific error.

### Explicitly excluded classes via `@source not inline('…')`

Or via the legacy `blocklist` from a JS config.

If you then have the following file:
```css
@import "tailwindcss";

@source not inline('bg-white');

.foo {
  @apply bg-white;
}
```

Then this will now result in:
```
Cannot apply utility class `bg-white` because it has been explicitly disabled: https://tailwindcss.com/docs/detecting-classes-in-source-files#explicitly-excluding-classes
```

We do this by checking if the class was marked as invalid.

### Applying unprefixed class in prefix mode

If you have the prefix option configured, but you are applying a
non-prefixed class, then we will show the following error:

Given this input:
```css
@import "tailwindcss" prefix(tw);

.foo {
  @apply underline;
}
```


The following error is thrown:
```
Cannot apply unprefixed utility class `underline`. Did you mean `tw:underline`?
```

### Applying known utilities with unknown variants

If you have unknown variants, then we will list them as well if the base
utility does compile correctly.

Given this input:

```css
@import "tailwindcss";

.foo {
  @apply hocus:hover:pocus:bg-red-500;
}
```

The following error is thrown:
```
Cannot apply utility class `hocus:hover:pocus:bg-red-500` because the `hocus` and `pocus` variants do not exist.
```

## Test plan

1. Everything behaves the same, but the error messages give more
details.
2. Updated tests with new error messages
3. Added new unit tests to verify the various scenarios
4. Added a Vue specific integration test with a `<style>…</style>` block
using `@apply`

[ci-all] There are some newlines here and there, let's verify that they
work identically on all platforms.

Fix migrating mt-[0px] to -mt-[0px] instead of the other way around (#18154)
I was testing to upgrade tool on various random projects just to see how
it behaves. Then I noticed an odd migration...

This PR fixes an issue where the upgrade tool accidentally migrated
classes such as `mt-[0px]` to `-mt-[0px]`. The reason for this is
because we are trying to find a replacement, and the computed signature
for both of them are exactly the same.

- `mt-[0px]` translates to:

   ```css
   .x {
     margin-top: 0px;
   }
   ```

- `-mt-[0px]` translates to:

   ```css
   .x {
     margin-top: calc(0px * -1);
   }
   ```

   Which in turn translates to

   ```css
   .x {
     margin-top: 0px;
   }
   ```

   Notice that this is `0px`, not `-0px`.

Internally we use the roots of functional utilities to find
replacements. For intellisense purposes we typically show negative
versions before positive versions. This then means that we will try
`-mt-*` before `mt-*`. Because of the signature above, the `mt-[0px]`
was translated into `-mt-[0px]`.

We could solve this in a few ways. The first thing we can try is to make
sure that the signature is not the same and that `-mt-[0px]` actually
translates into `-0px` not `0px`.

This would solve our problem of the accidental migration. However, if we
_just_ sort the functional utilities roots such that the positive
versions exist before negative version and rely on the fact that
`-mt-[0px]` has the same signature. Then it also means that by doing
that we can migrate `-mt-[0px]` into `mt-[0px]` which is even better
because it's the same result and shorter.

## Test plan

1. Added a test to verify that `mt-[0px]` does not get migrated to
`-mt-[0px]`.
2. Added a test to verify that `-mt-[0px]` does get migrated to
`mt-[0px]`.

Fix "Cannot read properties of undefined" crash on malformed arbitrary value (#18133)
This PR fixes a crash when an arbitrary value was malformed and crashed
the build.

If you have a utility like `[--btn-border:var(--color-maroon)/90)]`
which is malformed, it will crash the build. It might not be easy to
spot but the easy is the additional `)` after the `90`.

The reason this crashes is because we parse the value
`var(--color-maroon)/90)` and when we see `)` we assume it's the end of
a "function" which also assumes it was preceded by a `(`. This is not
the case and we crash.

This PR fixes that by not assuming the parsed object is available and
uses `?` to be safe and only access `nodes` if it's available.

I'm actually not 100% sure what the best solution is in this scenario
because these candidates could (and will) be returned from Oxide so even
if we throw a more descriptive error, it will still crash the build and
you might not even have control over the candidate.

This candidate will now eventually generate the following CSS:
```css
.\[--btn-border\:var\(--color-maroon\)\/90\)\] {
  --btn-border: var(--color-maroon) / ;
}
```

Which still looks odd, but even Lightning CSS doesn't throw an error in
this case (because it's a CSS variable definition), so I think it's the
best we can do. If you open your devtools you will see the weird values,
so it's still debug-able.

Fixes: #17064

## Test plan

Manually tested the candidate that crashed it, and after the change
generated the above CSS. Then used it in JSFiddle to proof it's fixed
now. https://jsfiddle.net/z850ykew/

Couldn't use Tailwind Play because the candidate will cause a crash
there as well 😅
