## Description

Always invoke when the user's message includes 'tailwind' in any form. Also invoke for: building responsive grid layouts (multi-column card grids, product grids), flex/grid page structures (dashboards with sidebars, fixed topbars, mobile-toggle navs), styling UI components (cards, tables, navbars, pricing sections, forms, inputs, badges), adding dark mode variants, fixing spacing or typography, and Tailwind v3/v4 work. The core use case: writing or fixing Tailwind utility classes in HTML templates (Blade, JSX, Vue). Skip for backend PHP logic, database queries, API routes, JavaScript with no HTML/CSS component, CSS file audits, build tool configuration, and vanilla CSS.

# Tailwind CSS Development

## Documentation

Use `search-docs` for detailed Tailwind CSS v4 patterns and documentation.

## Basic Usage

- Use Tailwind CSS classes to style HTML. Check and follow existing Tailwind conventions in the project before introducing new patterns.
- Offer to extract repeated patterns into components that match the project's conventions (e.g., Blade, JSX, Vue).
- Consider class placement, order, priority, and defaults. Remove redundant classes, add classes to parent or child elements carefully to reduce repetition, and group elements logically.

## Tailwind CSS v4 Specifics

- Always use Tailwind CSS v4 and avoid deprecated utilities.
- `corePlugins` is not supported in Tailwind v4.

### CSS-First Configuration

In Tailwind v4, configuration is CSS-first using the `@theme` directive, no separate `tailwind.config.js` file is needed:

<!-- CSS-First Config -->
```css
@theme {
  --color-brand: oklch(0.72 0.11 178);
}
```

### Import Syntax

In Tailwind v4, import Tailwind with a regular CSS `@import` statement instead of the `@tailwind` directives used in v3:

<!-- v4 Import Syntax -->
```diff
- @tailwind base;
- @tailwind components;
- @tailwind utilities;
+ @import "tailwindcss";
```

### Replaced Utilities

Tailwind v4 removed deprecated utilities. Use the replacements shown below. Opacity values remain numeric.

| Deprecated | Replacement |
|------------|-------------|
| bg-opacity-* | bg-black/* |
| text-opacity-* | text-black/* |
| border-opacity-* | border-black/* |
| divide-opacity-* | divide-black/* |
| ring-opacity-* | ring-black/* |
| placeholder-opacity-* | placeholder-black/* |
| flex-shrink-* | shrink-* |
| flex-grow-* | grow-* |
| overflow-ellipsis | text-ellipsis |
| decoration-slice | box-decoration-slice |
| decoration-clone | box-decoration-clone |

## Spacing

Use `gap` utilities instead of margins for spacing between siblings:
