Tailwind CSS Complete Guide

Introduction

Tailwind CSS is a utility-first CSS framework that allows rapid UI development with minimal custom CSS. This guide covers setup, core concepts, responsive design, and real-world examples.

Step 1: Setting Up Tailwind CSS

Install Tailwind via npm:

npm install -D tailwindcss postcss autoprefixer
npx tailwindcss init -p

Add Tailwind directives to your CSS:

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

Step 2: Core Concepts

Tailwind provides utility classes for:

• Spacing: p-4, m-2, mt-6
• Typography: text-lg, font-bold, text-gray-700
• Colors: bg-blue-500, text-white
• Flex & Grid: flex, grid, gap-4

Step 3: Responsive Design

Use responsive prefixes: sm:, md:, lg:, xl::

<div class="p-4 sm:p-6 md:p-8 lg:p-10">
  Responsive padding example
</div>

Step 4: Components

Tailwind encourages reusable components:

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

Step 5: Customization

Edit tailwind.config.js to extend theme, colors, or breakpoints:

module.exports = {
  theme: {
    extend: {
      colors: {
        primary: '#1DA1F2',
        secondary: '#14171A',
      },
    },
  },
}

Step 6: Practical Example – Responsive Card

<div class="max-w-sm mx-auto bg-white rounded-xl shadow-md overflow-hidden md:max-w-2xl">
  <div class="md:flex">
    <div class="md:flex-shrink-0">
      <img class="h-48 w-full object-cover md:h-full md:w-48" src="https://via.placeholder.com/150" alt="Placeholder"/>
    </div>
    <div class="p-8">
      <h2 class="uppercase tracking-wide text-sm text-indigo-500 font-semibold">Tailwind Card</h2>
      <p class="mt-2 text-gray-500">A practical example of a responsive card component using Tailwind CSS utilities.</p>
