Tailwind CSS

Utility-first CSS framework for rapid UI development with composable class names.

Overview

Tailwind CSS is a utility-first CSS framework that lets you build modern websites by composing utility classes directly in your HTML markup. Instead of writing custom CSS, you apply pre-built classes like `flex`, `pt-4`, and `rotate-90` to style elements, making it faster to prototype and ship designs without leaving your HTML.

The framework is built for the modern web, leveraging the latest CSS features including responsive design, CSS variables, P3 colors, CSS Grid, transitions, cascade layers, container queries, and 3D transforms. Tailwind automatically removes unused CSS during production builds, resulting in minimal bundle sizes—most projects ship less than 10kB of CSS.

Tailwind Plus, a companion product, offers hundreds of ready-made UI components and templates to accelerate development further.
