Tailwind CSS Best Practices for 2024

Introduction

Tailwind CSS has become the go-to CSS framework for modern web development. But with great power comes great responsibility. Let's explore best practices to keep your Tailwind code clean and maintainable.

1. Use Component Patterns

Instead of repeating classes, extract components:

jsx

 1// ❌ Bad: Repeating classes everywhere
 2<button className="px-4 py-2 bg-blue-500 hover:bg-blue-600 text-white rounded-lg font-medium transition-colors">
 3  Save
 4</button>
 5<button className="px-4 py-2 bg-blue-500 hover:bg-blue-600 text-white rounded-lg font-medium transition-colors">
 6  Submit
 7</button>
 8
 9// ✅ Good: Extract a component
10function Button({ children, ...props }) {
11  return (
12    <button 
13      className="px-4 py-2 bg-blue-500 hover:bg-blue-600 text-white rounded-lg font-medium transition-colors"
14      {...props}
15    >
16      {children}
17    </button>
18  );
19}

2. Leverage @apply Sparingly

Use @apply only for highly reused patterns:

css

 1/ globals.css /
 2@layer components {
 3  .btn-primary {
 4    @apply px-4 py-2 bg-blue-500 hover:bg-blue-600 text-white rounded-lg font-medium transition-colors;
 5  }
 6  
 7  .card {
 8    @apply bg-white rounded-xl shadow-lg p-6 border border-gray-100;
 9  }
10}

3. Custom Theme Configuration

Extend Tailwind with your design tokens:

javascript

 1// tailwind.config.js
 2module.exports = {
 3  theme: {
 4    extend: {
 5      colors: {
 6        brand: {
 7          50: '#f0fdf4',
 8          500: '#22c55e',
 9          900: '#14532d',
10        },
11      },
12      fontFamily: {
13        sans: ['Inter', 'sans-serif'],
14      },
15      animation: {
16        'fade-in': 'fadeIn 0.3s ease-in-out',
17      },
18      keyframes: {
19        fadeIn: {
20          '0%': { opacity: '0' },
21          '100%': { opacity: '1' },
22        },
23      },
24    },
25  },
26};

4. Responsive Design Patterns

Use mobile-first approach:

html

 1<!-- Mobile first: single column, then expand -->
 2<div className="grid grid-cols-1 md:grid-cols-2 lg:grid-cols-3 gap-6">
 3  <Card />
 4  <Card />
 5  <Card />
 6</div>

5. Dark Mode

Implement dark mode with CSS variables:

css

 1@layer base {
 2  :root {
 3    --background: 255 255 255;
 4    --foreground: 0 0 0;
 5  }
 6  
 7  .dark {
 8    --background: 10 10 10;
 9    --foreground: 255 255 255;
10  }
11}

javascript

 1// tailwind.config.js
 2module.exports = {
 3  darkMode: 'class',
 4  theme: {
 5    extend: {
 6      colors: {
 7        background: 'rgb(var(--background))',
 8        foreground: 'rgb(var(--foreground))',
 9      },
10    },
11  },
12};

6. Performance Tips

Use PurgeCSS (built into Tailwind)

Avoid dynamic class names
Use the JIT engine (default in v3+)

jsx

 1// ❌ Bad: Dynamic classes won't be purged
 2<div className={text-${color}-500}>
 3
 4// ✅ Good: Use complete class names
 5const colorClasses = {
 6  red: 'text-red-500',
 7  blue: 'text-blue-500',
 8};
 9<div className={colorClasses[color]}>

Conclusion

Following these best practices will help you write cleaner, more maintainable Tailwind CSS code. Remember: Tailwind is a tool – how you use it determines the quality of your codebase.
