Closes#17508
This PR fixes another issue we found that caused dev builds with Next.js
and Turbopack to resolve the CSS file that was saved one revision before
the latest update.
When debugging this we noticed that the PostCSS entry is called twice
for every one update when changing the input CSS file directly. That was
caused by the input file itself being added as a _dependency_ so you
would first get the callback that a _dependency_ has updated (at which
point we look at the file system and figure out we need a full-rebuild
because the input.css file has changed) and then another callback for
when the _input file_ has updated. The problem with the second callback
was that the file-system was already scanned for updates and since this
includes the `mtimes` for the input file, we seemingly thought that the
input file did not change. However, the issue is that the first callback
actually came with an outdated PostCSS input AST...
We found that this problem arises when you register the input CSS as a
dependency of itself. This is not expected and we actually guard against
this in the PostCSS client. However, we found that the input `from`
argument is _a relative path when using Next.js with Turbopack_ so that
check was not working as expected.
## Test plan
Added the change to the repro from #17508 and it seems to work fine now.
https://github.com/user-attachments/assets/2acb0078-f961-4498-be1a-b1c72d5ceda1
Also added a unit test to ensure we document that the input file path
can be a relative path.

This PR fixes an issue where if you use Next.js with `--turbopack` a
race condition happens because the `@tailwindcss/postcss` plugin is
called twice in rapid succession.
The first call sees an update and does a partial update with the new
classes. Next some internal `mtimes` are updated. The second call
therefore doesn't see any changes anymore because the `mtimes` are the
same, therefore it's serving its stale data.
Fixes: #17508
## Test plan
- Tested with the repro provided in #17508
- Added a new unit test that calls into the PostCSS plugin directly for
the same change from the same JavaScript run-loop.

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-to-position {

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 reworks a unit test that created a file in the project root and
then proceeded by scanning everything in the git root for candidates.
The issue specifically is that with the `.debug/` folder, our project
root can grow quite a bit which makes this test slower the more you work
on other tests...
To fix this we now simply create a tmp folder with only that one test
file. 🚀
Fixes#16725
When using `@reference "tailwindcss";` inside a separate CSS root (e.g.
Svelte `<style>` components, CSS modules, etc.), we have no guarantee
that the CSS variables will be defined in the main stylesheet (or if
there even is one). To work around potential issues with this we decided
in #16676 that we would emit all used CSS variables from the `@theme`
inside the `@reference` block.
However, this is not only a bit surprising but also unexpected in CSS
modules and Next.js that **requires CSS module files to only create
scope-able declarations**. To fix this issue, we decided to not emit CSS
variables but instead ensure all `var(…)` calls we create for theme
values in reference mode will simply have their fallback value added.
This ensures styles work as-expected even if the root Tailwind file does
not pick up the variable as being used or _if you don't add a root at
all_. Furthermore we do not duplicate any variable declarations across
your stylesheets and you still have the ability to change variables at
runtime.
## Test plan
- Updated snapshots everywhere (see diff)
- New Next.js CSS modules integration test
This PR re-enables the changes necessary to remove unused theme
variables and keyframes form your CSS.
This change was initially landed as #16211 and then later reverted in
#16403 because we found some unexpected interactions with using `@apply`
and CSS variables in multi-root setups like CSS modules or Vue inline
`<style>` blocks that were no longer seeing their required variables
defined.
This issue is fixed by now ensuring that theme variables that are
defined within an `@reference "…"` boundary will still be emitted in the
generated CSS when used (as this would otherwise not generate a valid
stylesheet).
So given the following input CSS:
```css
@reference "tailwindcss";
.text-red {
@apply text-red-500;
}
```
We will now compile this to:
```css
@layer theme {
:root, :host {
--text-red-500: oklch(0.637 0.237 25.331);
}
}
.text-red {
color: var(--text-red-500);
}
```
This PR also improves the initial implementation to not mark theme
variables as used if they are only used to define other theme variables.
For example:
```css
@theme {
--font-sans:
ui-sans-serif, system-ui, sans-serif, 'Apple Color Emoji', 'Segoe UI Emoji', 'Segoe UI Symbol',
'Noto Color Emoji';
--font-mono:
ui-monospace, SFMono-Regular, Menlo, Monaco, Consolas, 'Liberation Mono', 'Courier New',
monospace;
--default-font-family: var(--font-sans);
--default-mono-font-family: var(--font-mono);
}
.default-font-family {
font-family: var(--default-font-family);
}
```
This would be reduced to the following now as `--font-mono` is only used
to define another variable and never used outside the theme block:
```css
:root, :host {
--font-sans:
ui-sans-serif, system-ui, sans-serif, 'Apple Color Emoji', 'Segoe UI Emoji', 'Segoe UI Symbol',
'Noto Color Emoji';
--default-font-family: var(--font-sans);
}
.default-font-family {
font-family: var(--default-font-family);
}
```
## Test plan
- See updated unit and integration tests
- Validated it works end-to-end by using a SvelteKit example
This reverts #16211
We found some unexpected interactions with using `@apply` and CSS
variables in multi-root setups like CSS modules or Vue inline `<style>`
blocks that were broken due to that change. We plan to re-enable this
soon and include a proper fix for those scenarios.
## Test plan
- Updated snapshots
- Tested using the CLI in a new project:

This PR fixes an issue where if you only used `@reference` that we
didn't process Tailwind CSS features.
We have a 'quick bail check', in the PostCSS plugin to quickly bail if
we _konw_ that we don't need to handle any Tailwind CSS features. This
is useful in Next.js applications where every single CSS file will be
passed to the PostCSS plugin.
If you use custom font ins Next.js, each of those fonts will have a CSS
file as well.
Before we introduced `@reference`, we used `@import "tailwindcss"
reference`, which passed the bail check because `@import` was being
used. Now we have `@reference` which wasn't included in the list.
This is now solved.
Fixes: #16056
### Test plan
Added a failing test that is now failing after the fix.
Resolves#15799Resolves#14478
Part-of #15005
Adds a `:host` selector for the `@theme` layer. This is necessary for
the `@theme` layer to work correctly in shadow DOM.
Also updates the snapshots for the tests that were affected by this
change (in a separate commit).
## Test plan
Tested via the Vite playground:
<img width="1121" alt="Screenshot 2025-01-29 at 15 06 49"
src="https://github.com/user-attachments/assets/a7908135-5ff8-472f-a053-d2c6d5c81e1b"
/>
Additionally made sure that `@property` defaults also work across
Firefox, Chrome, and Safari (the `@property` definition from the root is
pulled in) and added a UI spec.

Closes#15138
This PR changes the postcss client to run in the `Once` hook instead of
`OnceExit`. This makes sure the postcss order in v4 matches that of v3.
Conceptually this also makes more sense, since we expect tailwindcss to
be run as one of the first plugins in the pipeline (where `OnceExit`
would run it almost at the end).
To make sure it's still possible to use `postcss-import` before and have
it resolve to the right paths, we also needed to change the
`postcss-fix-relative-paths` plugin to run in the `Once` order
(`postcss-import` also uses `Once` order so the order).
## Test Plan
This issue had many ways in which it can manifest. I added a unit test
to ensure the plugin order works but here's a concrete example when
using the postcss plugin in Vite.
### Before
Image `url()`s were not properly handled since the postcss plugin to
transform these was run before Tailwind CSS could generate the class for
it:

This PR improves the performance of the `@tailwindcss/postcss` and
`@tailwindcss/vite` implementations.
The issue is that in some scenarios, if you have multiple `.css` files,
then all of the CSS files are ran through the Tailwind CSS compiler. The
issue with this is that in a lot of cases, the CSS files aren't even
related to Tailwind CSS at all.
E.g.: in a Next.js project, if you use the `next/font/local` tool, then
every font you used will be in a separate CSS file. This means that we
run Tailwind CSS in all these files as well.
That said, running Tailwind CSS on these files isn't the end of the
world because we still need to handle `@import` in case `@tailwind
utilities` is being used. However, we also run the auto source detection
logic for every CSS file in the system. This part is bad.
To solve this, this PR introduces an internal `features` to collect what
CSS features are used throughout the system (`@import`, `@plugin`,
`@apply`, `@tailwind utilities`, etc…)
The `@tailwindcss/postcss` and `@tailwindcss/vite` plugin can use that
information to decide if they can take some shortcuts or not.
---
Overall, this means that we don't run the slow parts of Tailwind CSS if
we don't need to.

This PR changes how we render `var(...)` calls for theme values,
removing the fallback values we were previously including.
```diff
.text-white {
- color: var(--color-white, #fff);
+ color: var(--color-white);
}
```
We previously included the fallbacks only so you could see the value in
dev tools but this feels like a bad reason to bloat the CSS. I'd rather
just convince the Chrome team to surface this stuff better in dev tools
in the first place.

This PR updates all of the colors in our default theme to use OKLCH
instead of RGB and increases the overall chroma to take advantage of the
wider color gamut.
Just a first draft based on @danhollick's initial work — expecting these
will be further refined before a stable release as we continue to test
them.

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.

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.

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.

This PR adds support for a new `inline` option when defining a `@theme`
block that tells Tailwind to use raw theme values for utilities instead
of referencing the corresponding generated CSS variable.
```css
/* Input */
@theme inline {
--color-red-500: #ef4444;
/* ... */
}
/* Example output */
:root {
--color-red-500: #ef4444;
}
.text-red-500 {
color: #ef4444;
}
```
This can be composed with the existing `reference` option in case you
want to define a `@theme` block as both `reference` (so the variables
aren't generated) and `inline`:
```css
/* Input */
@theme inline reference {
--color-red-500: #ef4444;
/* ... */
}
/* Example output */
.text-red-500 {
color: #ef4444;
}
```
Since you can have multiple `@theme` blocks, you can even define some
values normally and some as inline based on how you're using them. For
example you might want to use `inline` for defining literal tokens like
`--color-red-500`, but include the variable for tokens that you want to
be able to theme like `--color-primary`:
```css
/* Input */
@theme inline {
--color-red-500: #ef4444;
/* ... */
}
@theme {
--color-primary: var(--color-red-500);
}
/* Example output */
:root {
--color-red-500: #ef4444;
--color-primary: var(--color-red-500);
}
.text-red-500 {
color: #ef4444;
}
.text-primary {
color: var(--color-primary, var(--color-red-500));
}
```
## Breaking changes
Prior to this PR, you could `@import` a stylesheet that contained
`@theme` blocks as reference by adding the `reference` keyword to your
import:
```css
@import "./my-theme.css" reference;
```
Now that `reference` isn't the only possible option when declaring your
`@theme`, this syntax has changed to a new `theme(…)` function that
accepts `reference` and `inline` as potential space-separated values:
```css
@import "./my-theme.css";
@import "./my-theme.css" theme(reference);
@import "./my-theme.css" theme(inline);
@import "./my-theme.css" theme(reference inline);
```
If you are using the `@import … reference` option with an earlier alpha
release, you'll need to update your code to `@import … theme(reference)`
once this PR lands in a release.
## Motivation
This PR is designed to solve an issue pointed out in #14091.
Prior to this PR, generated utilities would always reference variables
directly, with the raw value as a fallback:
```css
/* Input */
@theme {
--color-red-500: #ef4444;
/* ... */
}
/* Example output */
:root {
--color-red-500: #ef4444;
}
.text-red-500 {
color: var(--color-red-500, #ef4444);
}
```
But this can create issues with variables resolving to an unexpected
value when a theme value is referencing another variable defined on
`:root`.
For example, say you have a CSS file like this:
```css
:root, .light {
--text-fg: #000;
}
.dark {
--text-fg: #fff;
}
@theme {
--color-fg: var(--text-fg);
}
```
Without `@theme inline`, we'd generate this output if you used the
`text-fg` utility:
```css
:root, .light {
--text-fg: #000;
}
.dark {
--text-fg: #fff;
}
:root {
--color-fg: var(--text-fg);
}
.text-fg {
color: var(--color-fg, var(--text-fg));

Now if you wrote this HTML, you're probably expecting your text to be
the dark mode color:
```html
<div class="dark">
<h1 class="text-fg">Hello world</h1>
</div>
```
But you'd actually get the light mode color because of this rule:
```css
:root {
--color-fg: var(--text-fg);
}
.text-fg {
color: var(--color-fg, var(--text-fg));
}
```
The browser will try to resolve the `--color-fg` variable, which is
defined on `:root`. When it tries to resolve the value, _it uses the
value of `var(--text-fg)` as it would resolve at `:root`_, not what it
would resolve to based on the element that has the `text-fg` class.
So `var(--color-fg)` resolves to `#000` because `var(--text-fg)`
resolved to `#000` at the point in the tree where the browser resolved
the value of `var(--color-fg)`.
By using `@theme inline`, the `.text-fg` class looks like this:
```css
.text-fg {
color: var(--text-fg);
}
```
With this definition, the browser doesn't try to resolve `--color-fg` at
all and instead resolves `--text-fg` directly which correctly resolves
to `#fff` as expected.

Last week we discussed bringing in some consistency for our non-public
npm packages in the repo. We discussed using custom namespaces (e.g.
`@tailwindcss-internal`) vs. simple prefixes but it does not matter too
much if we are both consistent with our pattern and it's easy for us to
see whether a plugin is public or not.
Since we have a mixture of public namespaced (`@tailwindcss/*`) and
non-namespaced (`tailwindcss`) packages, I think it would be best if we
use a prefix to signal internal dependencies. This PR proposes we use
`internal-*` as the prefix and renames `test-utils` to
`internal-example-plugin` (since, really, this package is just an
example for the Tailwind plugin system).
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.
* Add basic `addVariant` plugin support
* Return early
* Load plugins right away instead later
* Use correct type for variant name
* Preliminary support for addVariant plugins in PostCSS plugin
* Add test for compounding plugin variants
* Add basic `loadPlugin` support to Vite plugin
* Add basic `loadPlugin` support to CLI

* add `tailwindcss-test-utils` to `@tailwindcss/cli` and `@tailwindcss/vite`
* only add `tailwindcss-test-utils` to `tailwindcss` as a dev dependency
Because `src/io.ts` is requiring the plugin.
* move `tailwindcss-test-utils` to `@tailwindcss/postcss `
This is the spot where we actually need it.
* use newer pnpm version

* 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
