Tailwind CSS: A Complete Beginner’s Guide

Tailwind CSS is a utility-first CSS framework that helps developers create responsive and modern designs quickly without writing custom CSS from scratch.

What is Tailwind CSS?

Tailwind CSS provides low-level utility classes like flex, pt-4, text-center, and bg-blue-500 that you can directly apply in HTML.
This approach lets you style elements quickly without leaving your HTML file.

Example:

<button class="bg-blue-500 text-white px-4 py-2 rounded hover:bg-blue-600">
  Click Me
</button>

Why Use Tailwind CSS?

Faster Development: No need to write long CSS files.
Responsive by Default: Built-in responsive utilities like sm:, md:, and lg:.
Customizable: Configure colors, fonts, and spacing in tailwind.config.js.
Small Final Size: Uses PurgeCSS to remove unused styles in production.

How to Install Tailwind CSS

1. Using npm

npm install -D tailwindcss
npx tailwindcss init

Add Tailwind to your CSS file:

@tailwind base;
@tailwind components;
@tailwind utilities;

2. Using CDN (Quick Test)

<script src="https://cdn.tailwindcss.com"></script>

Tailwind CSS Core Concepts

Utility Classes – Example: mt-4 (margin-top), text-lg (large text).
Responsive Design – Prefix utilities: sm:bg-red-500, md:w-1/2.
State Variants – Hover, focus, active states: hover:bg-green-500.
Customization – Edit tailwind.config.js to add your own design system.

Example: Responsive Card with Tailwind CSS

<div class="max-w-sm mx-auto bg-white shadow-md rounded-lg overflow-hidden">
  <img src="image.jpg" alt="Sample" class="w-full">
  <div class="p-4">
    <h2 class="text-xl font-semibold mb-2">Card Title</h2>
    <p class="text-gray-600">This is a responsive card built with Tailwind CSS.</p>
    <button class="mt-4 bg-blue-500 text-white px-4 py-2 rounded hover:bg-blue-600">
