4. Core Concepts

4.1 Utility-First Workflow

Tailwind CSS promotes a utility-first workflow, where you build designs by combining small, single-purpose classes.

<div class="p-6 max-w-sm mx-auto bg-white rounded-xl shadow-md flex items-center space-x-4">
  <div class="flex-shrink-0">
    <img class="h-12 w-12" src="/img/logo.svg" alt="ChitChat Logo">
  </div>
  <div>
    <div class="text-xl font-medium text-black">ChitChat</div>
    <p class="text-gray-500">You have a new message!</p>
  </div>
</div>

4.2 Responsive Design

Tailwind makes it easy to build responsive designs with breakpoint prefixes:

<div class="w-full md:w-1/2 lg:w-1/3">
  <!-- This div will be full width on small screens, 1/2 width on medium screens, and 1/3 width on large screens -->
</div>

4.3 Hover, Focus, and Other States

Tailwind provides easy ways to style elements on different states:

<button class="bg-blue-500 hover:bg-blue-700 text-white font-bold py-2 px-4 rounded">
  Hover me
</button>

5. Advanced Topics

5.1 Custom Plugins

You can extend Tailwind's functionality by writing custom plugins:

// tailwind.config.js
const plugin = require('tailwindcss/plugin')

module.exports = {
  plugins: [
    plugin(function({ addUtilities }) {
      const newUtilities = {
        '.rotate-45': {
          transform: 'rotate(45deg)',
        },
        '.rotate-90': {
          transform: 'rotate(90deg)',
        },
      }
      addUtilities(newUtilities)
    })
  ]
}

5.2 PurgeCSS Integration

Tailwind integrates with PurgeCSS to remove unused styles in production:

// tailwind.config.js
module.exports = {
  purge: [
    './src/**/*.html',
    './src/**/*.js',
  ],
  // ...
}
