Tailwind CSS is a modern utility-first CSS framework used to build custom user interfaces quickly.
Instead of providing ready-made components like Bootstrap, Tailwind gives small utility classes for spacing, colors, typography, flexbox, grid, responsiveness, shadows, animations, and more.
Developers combine these utility classes directly inside HTML to create fully custom designs.

Highly customizable design
Responsive utilities
Cleaner workflow
No need to write large CSS files
Modern frontend development support
Works perfectly with React and Next.js
What is Utility-First CSS?
Tailwind CSS uses small reusable utility classes instead of traditional CSS component styling.
Traditional CSS:
[code theme="dark"]
Button
[/code]
[code theme="dark"]
.btn{
background:blue;
color:white;
padding:12px 20px;
border-radius:8px;
}
[/code]
Tailwind CSS:
[code theme="dark"]
Button
[/code]
Everything is controlled directly using utility classes.
