Let’s get started and build a beautiful, responsive website fast with Tailwind CSS!


Project Setup and Tailwind CSS Installation

To get started with Tailwind CSS, we’ll create a simple project using HTML, Tailwind CLI, and a basic folder structure. This approach is perfect for beginners and doesn’t require any complex build tools.

Step 1: Create a New Project Folder

First, open your terminal and create a new folder for your project:

mkdir tailwind-crash-course
cd tailwind-crash-course

Inside this folder, create the following structure:

tailwind-crash-course/
├── index.html
├── styles/
│   └── input.css
├── dist/
│   └── output.css

Step 2: Initialize a New Node.js Project

To use Tailwind CLI, you need Node.js installed. If you don’t have it, you can download it here.

Then, initialize your project and install Tailwind:

npm init -y
npm install -D tailwindcss
npx tailwindcss init

This will create a tailwind.config.js file in your project root.

Step 3: Configure Tailwind

In your tailwind.config.js, set the content paths so Tailwind knows which files to scan for classes:

// tailwind.config.js
module.exports = {
  content: ["./index.html"],
  theme: {
    extend: {},
  },
  plugins: [],
}

Step 4: Add Tailwind Directives to CSS

In your styles/input.css, add the Tailwind directives:

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

Step 5: Build Tailwind CSS

Use the Tailwind CLI to compile your styles:

npx tailwindcss -i ./styles/input.css -o ./dist/output.css --watch

Step 6: Link CSS in HTML

Now, create a basic index.html and link the generated Tailwind CSS file:

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8" />
  <meta name="viewport" content="width=device-width, initial-scale=1.0" />
  <title>Tailwind CSS Crash Course</title>
  <link href="./dist/output.css" rel="stylesheet">
</head>
<body>
  <h1 class="text-3xl font-bold text-center mt-10">Hello, Tailwind CSS!</h1>
</body>
</html>

Open index.html in your browser, and you should see a bold, centered heading styled with Tailwind!

Building a Responsive Website Layout with Tailwind CSS

With Tailwind installed and ready, it's time to build a modern, responsive layout. We’ll create a simple webpage with:

  • A responsive header and navigation bar
  • A hero section with text and an image
  • Mobile-first responsiveness with Tailwind’s utility classes

Let’s dive in!

HTML Structure

Create a file called index.html and add the following base:

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8" />
  <meta name="viewport" content="width=device-width, initial-scale=1.0" />
  <title>Tailwind CSS Crash Course</title>
  <link href="output.css" rel="stylesheet" />
</head>
<body class="bg-gray-100 text-gray-900">
  <!-- Content will go here -->
</body>
</html>

Make sure output.css is the compiled Tailwind file (we’ll cover the build command in the next section if you need it).

Responsive Navbar

    <header class="bg-white shadow">
        <div class="container mx-auto px-4 py-4 flex justify-between items-center">
            <h1 class="text-xl font-bold text-blue-600">TailwindSite</h1>
            <nav class="space-x-4 hidden md:block">
            <a href="#" class="text-gray-700 hover:text-blue-600">Home</a>
            <a href="#" class="text-gray-700 hover:text-blue-600">About</a>
            <a href="#" class="text-gray-700 hover:text-blue-600">Contact</a>
            </nav>
            <!-- Mobile menu button -->
            <button class="md:hidden text-gray-700 focus:outline-none">
            <svg class="w-6 h-6" fill="none" stroke="currentColor"
                viewBox="0 0 24 24" xmlns="http://www.w3.org/2000/svg">
                <path stroke-linecap="round" stroke-linejoin="round"
                    stroke-width="2" d="M4 6h16M4 12h16M4 18h16"></path>
            </svg>
            </button>
        </div>
    </header>

This navbar is responsive:

  • On mobile, the links are hidden
  • On medium screens and up (md:), the links appear inline

Hero Section

<section class="bg-white py-16">
  <div class="container mx-auto px-4 flex flex-col-reverse md:flex-row items-center">
    <div class="w-full md:w-1/2">
      <h2 class="text-4xl font-bold mb-4">Build Fast with Tailwind CSS</h2>
      <p class="mb-6 text-gray-700">
        Learn how to build modern, responsive websites quickly and efficiently using Tailwind’s utility-first approach.
      </p>
      <a href="#" class="bg-blue-600 text-white px-6 py-3 rounded hover:bg-blue-700 transition">Get Started</a>
    </div>
    <div class="w-full md:w-1/2 mb-8 md:mb-0">
      <img src="https://via.placeholder.com/500x300" alt="Hero Image" class="w-full rounded shadow" />
    </div>
  </div>
</section>

Mobile-First by Default

Tailwind is mobile-first by design. You use responsive breakpoints like:

  • md: for tablets (768px and up)
  • lg: for desktops (1024px and up)

So everything stacks vertically on mobile and rearranges at larger screen sizes — no media queries needed!

Add This Footer Below Your Main Content

<footer class="bg-gray-800 text-white py-8 mt-16">
  <div class="container mx-auto px-4 text-center md:text-left md:flex md:justify-between">
    <div class="mb-6 md:mb-0">
      <h2 class="text-2xl font-bold text-blue-400 mb-2">TailwindSite</h2>
      <p class="text-gray-400 text-sm">Build fast, responsive websites with Tailwind CSS.</p>
    </div>
    <div class="space-y-2">
      <h3 class="text-lg font-semibold mb-2">Quick Links</h3>
      <ul class="text-gray-300 space-y-1">
        <li><a href="#" class="hover:text-white transition">Home</a></li>
        <li><a href="#" class="hover:text-white transition">About</a></li>
        <li><a href="#" class="hover:text-white transition">Contact</a></li>
      </ul>
    </div>
  </div>
  <div class="mt-8 text-center text-sm text-gray-500">
    &copy; 2025 TailwindSite. All rights reserved.
  </div>
</footer>

Notes:

  • It’s responsive: stacks on mobile, flexes on desktop.
  • Uses utility classes like bg-gray-800, text-white, and responsive spacing (md:*).
  • Clean and minimal — perfect for a crash course example.

Add a Scroll-to-Top Button

Place this button at the end of your body, right before the closing </body> tag:

<!-- Scroll to Top Button -->
<button id="scrollTopBtn"
  class="fixed bottom-6 right-6 z-50 hidden p-3 rounded-full bg-blue-600 text-white shadow-lg hover:bg-blue-700 transition duration-300"
  aria-label="Scroll to top">
  ↑
</button>

Add This Script Below the Button

This shows the button when scrolling down and scrolls smoothly to the top on click.

<script>
  const scrollTopBtn = document.getElementById("scrollTopBtn");

  window.addEventListener("scroll", () => {
    if (window.scrollY > 300) {
      scrollTopBtn.classList.remove("hidden");
    } else {
      scrollTopBtn.classList.add("hidden");
    }
  });

  scrollTopBtn.addEventListener("click", () => {
    window.scrollTo({ top: 0, behavior: "smooth" });
  });
</script>

Features:

  • Tailwind for styling (fixed, bottom-6, rounded-full, hover:bg-blue-700)
  • Responsive and smooth UX
  • Hidden by default and appears after scrolling 300px down


Tailwind CSS CLI Build Process: From Utility to Production

Now that we’ve built our layout using Tailwind’s utility classes, it’s time to compile our CSS using the Tailwind CLI. This step generates a stylesheet (output.css) that includes only the utilities we used, keeping the final CSS small and fast.

1. Create Your Input CSS File

Inside your project folder, create a file named input.css and add this:

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

This tells Tailwind what layers to include in your final build.

2. Make Sure Your Project Structure Looks Like This

tailwind-crash-course/
├── index.html
├── input.css
├── tailwind.config.js  (optional, if you created one)
└── output.css          (will be generated)

3. Run the Tailwind CLI Build Command

Use this command to compile your CSS (you can run it once for now):

npx tailwindcss -i ./input.css -o ./output.css --minify

Explanation:

  • -I specify the input file
  • -o specifies the output file
  • --minify reduces the file size for production use

4. (Optional) Add a Watch Command for Development

If you want to auto-rebuild CSS on changes, run:

npx tailwindcss -i ./input.css -o ./output.css --watch

This watches your index.html and input.css for changes and updates output.css automatically.

5. Link the Output CSS in Your HTML

Make sure this is in the <head> of your index.html:

<link href="output.css" rel="stylesheet" />

Now, when you open index.html in the browser, your Tailwind styles should be applied!


Conclusion: Fast-Track Your Frontend with Tailwind CSS
