# Tailwind CSS Development Patterns

Expert guide for building modern, responsive user interfaces with Tailwind CSS utility-first framework. Covers v4.1+ features including CSS-first configuration, custom utilities, and enhanced developer experience.

## Overview

Provides actionable patterns for responsive, accessible UIs with Tailwind CSS v4.1+. Covers utility composition, dark mode, component patterns, and performance optimization.

## When to Use

- Styling React/Vue/Svelte components
- Building responsive layouts and grids
- Implementing design systems
- Adding dark mode support
- Optimizing CSS workflow

## Quick Reference

### Responsive Breakpoints

| Prefix | Min Width | Description |
|--------|-----------|-------------|
| `sm:` | 640px | Small screens |
| `md:` | 768px | Tablets |
| `lg:` | 1024px | Desktops |
| `xl:` | 1280px | Large screens |
| `2xl:` | 1536px | Extra large |

### Common Patterns

```html

<div class="flex items-center justify-center min-h-screen">
  Content
</div>

<div class="grid grid-cols-1 sm:grid-cols-2 lg:grid-cols-4 gap-4">
  
</div>

<div class="bg-white rounded-lg shadow-lg p-6">
  <h3 class="text-xl font-bold">Title</h3>
  <p class="text-gray-600">Description</p>
</div>
```

## Instructions

1. **Start Mobile-First**: Write base styles for mobile, add responsive prefixes (`sm:`, `md:`, `lg:`) for larger screens
2. **Use Design Tokens**: Leverage Tailwind's spacing, color, and typography scales
3. **Compose Utilities**: Combine multiple utilities for complex styles
4. **Extract Components**: Create reusable component classes for repeated patterns
5. **Configure Theme**: Customize design tokens in `tailwind.config.js` or using `@theme`
6. **Verify Changes**: Test at each breakpoint using DevTools responsive mode. Check for visual regressions and accessibility issues before committing.

## Examples

### Responsive Card Component

```tsx
function ProductCard({ product }: { product: Product }) {
  return (
    <div className="bg-white rounded-lg shadow-lg overflow-hidden sm:flex">
      <img className="h-48 w-full object-cover sm:h-auto sm:w-48" src={product.image} />
      <div className="p-6">
        <h3 className="text-lg font-semibold">{product.name}</h3>
        <button className="mt-4 px-4 py-2 bg-indigo-600 text-white rounded-lg hover:bg-indigo-700">
          Add to Cart
        </button>
      </div>
    </div>
  );
}
```

### Dark Mode Toggle

```html
<div class="bg-white dark:bg-gray-900 text-gray-900 dark:text-white">
  <h1 class="dark:text-white">Title</h1>
</div>
```

### Form Input

```html
<input
  class="w-full px-4 py-2 border border-gray-300 rounded-lg focus:ring-2 focus:ring-blue-500 focus:border-transparent"
  placeholder="you@example.com"
/>
```

## Best Practices

1. **Consistent Spacing**: Use Tailwind's spacing scale (4, 8, 12, 16, etc.)
2. **Color Palette**: Stick to Tailwind's color system for consistency
3. **Component Extraction**: Extract repeated patterns into reusable components
4. **Utility Composition**: Prefer utility classes over `@apply` for maintainability
5. **Semantic HTML**: Use proper HTML elements with Tailwind classes
6. **Performance**: Ensure content paths include all template files for optimal purging
7. **Accessibility**: Include focus styles, ARIA labels, and respect user preferences (reduced-motion)

## Troubleshooting

### Classes Not Applying
- **Check content paths**: Ensure all template files are included in `content: []` in config
- **Verify build**: Run `npm run build` to regenerate purged CSS
- **Dev mode**: Use `npx tailwindcss -o` with `--watch` flag for live updates

### Responsive Styles Not Working
- **Order matters**: Responsive prefixes must come before non-responsive (e.g., `md:flex` not `flex md:flex`)
- **Check breakpoint values**: Verify breakpoints match your design requirements
- **DevTools**: Use browser DevTools responsive mode to test at each breakpoint

### Dark Mode Issues
- **Verify config**: Ensure `darkMode: 'class'` or `'media'` is set correctly
- **Toggle implementation**: Use `document.documentElement.classList.toggle('dark')` for class strategy
- **Initial flash**: Add `dark` class to `<html>` before body renders

## Constraints and Warnings

- **Class Proliferation**: Long class strings reduce readability; extract into components
- **Content Paths**: Misconfigured paths cause classes to be purged in production
- **Arbitrary Values**: Use sparingly; prefer design tokens for consistency
- **Specificity Issues**: Avoid `@apply` with complex selectors
- **Dark Mode**: Requires correct configuration (`class` or `media` strategy)
- **Browser Support**: Check Tailwind docs for compatibility notes
