1. Overview of Tailwind CSS 4.0

What is Tailwind CSS?

Tailwind CSS is a widely used CSS framework in modern web development, based on a utility-first approach. Instead of writing custom CSS, developers can build consistent and efficient UIs using predefined utility classes.

Key Changes in Version 4.0

Tailwind CSS 4.0 includes several significant updates. Build speed has been improved, unused styles are automatically purged to optimize file size, and new classes have been introduced to facilitate responsive design.

2. New Utility Classes

Improved Layout Classes

New flexbox and grid classes have been introduced to simplify layout configuration.

<div class="grid grid-cols-auto gap-4">
    <div class="bg-blue-500 p-4 rounded-lg shadow-md">Item 1</div>
    <div class="bg-green-500 p-4 rounded-lg shadow-md">Item 2</div>
    <div class="bg-red-500 p-4 rounded-lg shadow-md">Item 3</div>
</div>

Optimized Responsive Design

New responsive classes make it easier to create flexible UIs across various devices.

<div class="w-full sm:w-1/2 md:w-1/3 lg:w-1/4 xl:w-1/6">Responsive Element</div>

New Colors and Gradient Support

More color palettes and gradient options have been added.

<div class="bg-gradient-to-r from-purple-400 to-pink-500 p-6 text-white font-bold text-xl">
    Beautiful Gradient Effect
</div>

3. Updated Design Patterns

Component Styling Trends

New classes allow for better control over hover, focus, and active states.

<button class="bg-blue-500 hover:bg-blue-700 focus:ring-4 focus:ring-blue-300 text-white font-bold py-2 px-4 rounded-lg transition-all">
    Interactive Button
</button>

Enhanced Plugin and Extension Support

The plugin system has been made more flexible, allowing developers to create custom extensions easily.

// tailwind.config.js
module.exports = {
  theme: {
    extend: {
      spacing: {
        '128': '32rem',
