Introduction to Tailwind CSS

Tailwind CSS is a Utility-First CSS Framework that allows developers to build modern, responsive, and customizable user interfaces directly from HTML using predefined utility classes.

Unlike Bootstrap, which provides ready-made components such as cards and navbars, Tailwind provides low-level utility classes that give developers complete control over design.

Example:

<div class="bg-blue-500 text-white p-4 rounded-lg">
    Hello Tailwind CSS
</div>

Without writing custom CSS, Tailwind automatically applies:

Background Color
Text Color
Padding
Border Radius

Why Tailwind CSS?

Faster UI Development

Build interfaces directly in HTML.

Highly Customizable

Modify colors, spacing, breakpoints, typography, and themes.

Smaller Production Files

Unused CSS can be removed automatically.

Responsive by Default

Built-in responsive utilities simplify mobile-first development.

Modern Development Workflow

Widely used with:

React
Next.js
Vue
Angular
Laravel
