Study Notes: Introduction to Tailwind CSS

💡 Easy English Concept Guide

Tailwind CSS lets you style a website by adding utility classes (ready-to-use style labels) directly to your HTML elements, bypassing traditional external styles.

1. What is Utility-First Styling?

Instead of writing custom CSS classes like .profile-card { background: white; padding: 16px; }, Tailwind CSS provides pre-defined utility classes that you apply directly inline inside your elements.

2. Installation & Sandbox Integration

To use Tailwind instantly in any independent HTML file, you import the Tailwind CDN script inside your head section:

<!DOCTYPE html>
<html>
<head>
    <!-- Import Tailwind CDN -->
    <script src="https://cdn.tailwindcss.com"></script>
</head>
<body class="bg-slate-100 flex items-center justify-center min-h-screen">
    <div class="bg-white p-8 rounded-3xl shadow-xl max-w-sm text-center">
        <h2 class="text-2xl font-black text-indigo-600">Tailwind Test</h2>
        <p class="text-slate-500 text-sm mt-2">Fast styling directly inside the HTML.</p>
    </div>
</body>
</html>

💡 Quick Revision Guide

Ensure your layouts adapt cleanly across responsive viewport widths. Double-check script sequences to verify that DOM selections happen after nodes are parsed by the browser.
