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
<!-- Center content -->
<div class="flex items-center justify-center min-h-screen">
Content
</div>
<!-- Responsive grid -->
<div class="grid grid-cols-1 sm:grid-cols-2 lg:grid-cols-4 gap-4">
<!-- Items -->
</div>
<!-- Card component -->
<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
- Start Mobile-First: Write base styles for mobile, add responsive prefixes (
sm:,md:,lg:) for larger screens - Use Design Tokens: Leverage Tailwind's spacing, color, and typography scales
- Compose Utilities: Combine multiple utilities for complex styles
- Extract Components: Create reusable component classes for repeated patterns
- Configure Theme: Customize design tokens in
tailwind.config.jsor using@theme - Verify Changes: Test at each breakpoint using DevTools responsive mode. Check for visual regressions and accessibility issues before committing.
Examples
Responsive Card Component
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
<div class="bg-white dark:bg-gray-900 text-gray-900 dark:text-white">
<h1 class="dark:text-white">Title</h1>
</div>Form Input
<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
- Consistent Spacing: Use Tailwind's spacing scale (4, 8, 12, 16, etc.)
- Color Palette: Stick to Tailwind's color system for consistency
- Component Extraction: Extract repeated patterns into reusable components
- Utility Composition: Prefer utility classes over
@applyfor maintainability - Semantic HTML: Use proper HTML elements with Tailwind classes
- Performance: Ensure content paths include all template files for optimal purging
- 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 buildto regenerate purged CSS - Dev mode: Use
npx tailwindcss -owith--watchflag for live updates
Responsive Styles Not Working
- Order matters: Responsive prefixes must come before non-responsive (e.g.,
md:flexnotflex 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
darkclass 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
@applywith complex selectors - Dark Mode: Requires correct configuration (
classormediastrategy) - Browser Support: Check Tailwind docs for compatibility notes
