Your First Component

Welcome to Tailwind CSS

Tailwind CSS is a utility-first CSS framework. Instead of writing CSS rules, you apply pre-built utility classes directly in HTML:

<!-- Traditional CSS approach -->
<div class="card">Hello</div>

<!-- Tailwind approach -->
<div class="bg-blue-500 text-white p-4 rounded-lg font-bold">Hello</div>

Common utilities:

  • p-4 — padding: 1rem (16px)
  • m-2 — margin: 0.5rem
  • text-xl — font-size: 1.25rem
  • font-bold — font-weight: 700
  • bg-blue-500 — background: a blue color
  • text-white — color: white
  • rounded-lg — border-radius: 0.5rem
  • text-center — text-align: center

The number scale (100–900 for colors, 1–16 for spacing) gives you precise control.

Your Task

Create a styled <div> using at least: p-4, bg-blue-500, text-white, and rounded.
