Tailwind CSS IntelliSense enhances the Tailwind development experience by providing Visual Studio Code users with advanced features such as autocomplete, syntax highlighting, and linting.
## Installation
**[Install via the Visual Studio Code Marketplace →](https://marketplace.visualstudio.com/items?itemName=bradlc.vscode-tailwindcss)**
In order for the extension to activate you must have [`tailwindcss` installed](https://tailwindcss.com/docs/installation) and a [Tailwind config file](https://tailwindcss.com/docs/installation#create-your-configuration-file) named `tailwind.config.js` in your workspace.
## Features
### Autocomplete
Intelligent suggestions for class names, as well as [CSS functions and directives](https://tailwindcss.com/docs/functions-and-directives/).

### Linting
Highlights errors and potential bugs in both your CSS and your markup.

### Hover Preview
See the complete CSS for a Tailwind class name by hovering over it.

### CSS Syntax Highlighting
Provides syntax definitions so that Tailwind features are highlighted correctly.
## Recommended VS Code Settings
VS Code has built-in CSS validation which may display errors when using Tailwind-specific syntax, such as `@apply`. You can disable this with the `css.validate` setting:
```
"css.validate": false
```
By default VS Code will not trigger completions when editing "string" content, for example within JSX attribute values. Updating the `editor.quickSuggestions` setting may improve your experience:
```
"editor.quickSuggestions": {
"strings": true
}
```
## Extension Settings
### `tailwindCSS.includeLanguages`
This setting allows you to add additional language support. The key of each entry is the new language ID and the value is any one of the extensions built-in languages, depending on how you want the new language to be treated (e.g. `html`, `css`, or `javascript`):
```json
{
"tailwindCSS.includeLanguages": {
"plaintext": "html"
}
}
```
### `tailwindCSS.emmetCompletions`
Enable completions when using [Emmet](https://emmet.io/)-style syntax, for example `div.bg-red-500.uppercase`. **Default: `false`**
### `tailwindCSS.colorDecorators`
Controls whether the editor should render inline color decorators for Tailwind CSS classes and helper functions. **Default: `true`**
> Note that `editor.colorDecorators` must be enabled for color decorators to be shown.
### `tailwindCSS.showPixelEquivalents`
Show `px` equivalents for `rem` CSS values in completions and hovers. **Default: `true`**
### `tailwindCSS.rootFontSize`
Root font size in pixels. Used to convert `rem` CSS values to their `px` equivalents. See [`tailwindCSS.showPixelEquivalents`](#tailwindcssshowpixelequivalents). **Default: `16`**
### `tailwindCSS.validate`
Enable linting. Rules can be configured individually using the `tailwindcss.lint` settings:
- `ignore`: disable lint rule entirely
- `warning`: rule violations will be considered "warnings," typically represented by a yellow underline
- `error`: rule violations will be considered "errors," typically represented by a red underline
#### `tailwindCSS.lint.invalidScreen`
Unknown screen name used with the [`@screen` directive](https://tailwindcss.com/docs/functions-and-directives/#screen). **Default: `error`**
#### `tailwindCSS.lint.invalidVariant`
Unknown variant name used with the [`@variants` directive](https://tailwindcss.com/docs/functions-and-directives/#variants). **Default: `error`**
#### `tailwindCSS.lint.invalidTailwindDirective`
Unknown value used with the [`@tailwind` directive](https://tailwindcss.com/docs/functions-and-directives/#tailwind). **Default: `error`**
#### `tailwindCSS.lint.invalidApply`
Unsupported use of the [`@apply` directive](https://tailwindcss.com/docs/functions-and-directives/#apply). **Default: `error`**
#### `tailwindCSS.lint.invalidConfigPath`
Unknown or invalid path used with the [`theme` helper](https://tailwindcss.com/docs/functions-and-directives/#theme). **Default: `error`**
#### `tailwindCSS.lint.cssConflict`
Class names on the same HTML element which apply the same CSS property or properties. **Default: `warning`**
#### `tailwindCSS.lint.recommendedVariantOrder`
Class variants not in the recommended order (applies in [JIT mode](https://tailwindcss.com/docs/just-in-time-mode) only). **Default: `warning`**
### `tailwindCSS.inspectPort`
Enable the Node.js inspector agent for the language server and listen on the specified port. **Default: `null`**
## Troubleshooting
If you’re having issues getting the IntelliSense features to activate, there are a few things you can check:
- Ensure that you have a Tailwind config file in your workspace and that this is named `tailwind.config.js`. Check out the Tailwind documentation for details on [creating a config file](https://tailwindcss.com/docs/installation#create-your-configuration-file).
- Ensure that the `tailwindcss` module is installed in your workspace, via `npm`, `yarn`, or `pnpm`.
- Make sure your VS Code settings aren’t causing your Tailwind config file to be hidden/ignored, for example via the `files.exclude` or `files.watcherExclude` settings.
- Take a look at the language server output by running the `Tailwind CSS: Show Output` command from the command palette. This may show errors that are preventing the extension from activating.
