## What it is
Tailwind CSS is a utility-first CSS framework for rapidly building custom user interfaces directly in markup. It provides low-level utility classes composed via PostCSS-based tooling, with a companion typography plugin and JIT engine.

## Use cases
- style a website without writing custom css
- rapidly build responsive user interfaces
- create a consistent design system with utility classes
- prototype web app layouts quickly
- add dark mode and responsive breakpoints to a site
- build custom ui components with prebuilt utility classes

## When to choose
- you want utility-first styling co-located with your markup
- you need rapid, consistent responsive design across a project
- your team wants a well-maintained, widely adopted css framework

## When to avoid
- you prefer semantic, component-scoped css or css-in-js
- your project already uses another styling framework like Bootstrap
- you need zero build tooling and pure runtime css

## Facets
- artifact type: framework
- maturity: stable
- function: css-framework, ui-components, templating
- domain: web-development, frontend, web-design
- platform: cross-platform
