Introduction

We use Tailwind CSS to style websites quickly. You can add Tailwind either by linking to a CDN or by using a build tool. Each way has its own benefits and fits different needs.

You want to quickly try Tailwind CSS without setup.

You build a small website or prototype fast.

You want full control over your styles and optimize for speed.

You have a large project and want to remove unused styles.

You want to customize Tailwind deeply with plugins or config.

Syntax

Tailwind

/* Using CDN */
<link href="https://cdn.tailwindcss.com" rel="stylesheet">

/* Using Build Tool (example with npm and PostCSS) */
npm install -D tailwindcss postcss autoprefixer
npx tailwindcss init

/* In your CSS file */
@tailwind base;
@tailwind components;
@tailwind utilities;

CDN method is simple and fast but includes all Tailwind styles.

Build tool method requires setup but creates smaller, optimized CSS.

Examples

Quickly add Tailwind CSS to your HTML using CDN link.

Tailwind

<link href="https://cdn.tailwindcss.com" rel="stylesheet">

Configure Tailwind to scan your files and remove unused styles when using build tools.

Tailwind

/* tailwind.config.js */
module.exports = {
  content: ['./src/**/*.{html,js}'],
  theme: {
    extend: {},
  },
  plugins: [],
};

Include Tailwind layers in your CSS file for build tool processing.

Tailwind

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

Sample Program

This example shows how you can use Tailwind CSS either by linking a CDN or by setting up a build tool. The CDN method is fast but loads all styles. The build tool method takes time to set up but creates a smaller CSS file with only the styles you use.

Tailwind

/* Sample project setup comparison */

// Using CDN in HTML:
// <html>
// <head>
//   <script src="https://cdn.tailwindcss.com"></script>
// </head>
// <body>
//   <button class="bg-blue-500 text-white p-2 rounded">Click me</button>
// </body>
// </html>

// Using Build Tool:
// 1. Install Tailwind and dependencies
// 2. Create tailwind.config.js with content paths
// 3. Create styles.css with Tailwind directives
// 4. Run build command to generate output.css
// 5. Link output.css in HTML

// Result:
// CDN loads full Tailwind CSS (~3MB uncompressed), quick start.
// Build tool generates small CSS with only used styles (~10KB), faster load.

console.log("CDN method: quick start, full styles loaded.");
console.log("Build tool method: setup needed, optimized CSS output.");

Important Notes

CDN is great for learning and small projects but not ideal for production due to large file size.

Build tools help keep your CSS small and fast by removing unused styles.

Using build tools allows customization like adding plugins or changing default themes.

Summary

CDN method is simple and fast but loads all Tailwind styles.

Build tool method requires setup but creates optimized, smaller CSS.

Choose CDN for quick prototypes and build tools for scalable projects.
