## Features

Inspired by [Windi CSS](http://windicss.org/), [Tailwind CSS](https://tailwindcss.com/), and [Twind](https://github.com/tw-in-js/twind), but:

- [Fully customizable](https://unocss.dev/config/) - no core utilities. All functionalities are provided via presets.
- No parsing, no AST, no scanning, it's **INSTANT** (5x faster than Windi CSS or Tailwind JIT).
- ~6kb min+brotli - zero deps and browser friendly.
- [Shortcuts](https://unocss.dev/config/shortcuts) - aliasing utilities, dynamically.
- [Attributify mode](https://unocss.dev/presets/attributify/) - group utilities in attributes.
- [Pure CSS Icons](https://unocss.dev/presets/icons/) - use any icon as a single class.
- [Variant Groups](https://unocss.dev/transformers/variant-group) - shorthand for group utils with common prefixes.
- [CSS Directives](https://unocss.dev/transformers/directives) - reuse utils in CSS with `@apply` directive.
- [Compilation mode](https://unocss.dev/transformers/compile-class/) - synthesizes multiple classes into one at build time.
- [Inspector](https://unocss.dev/tools/inspector) - inspect and debug interactively.
- [CSS-in-JS Runtime build](https://unocss.dev/integrations/runtime) - use UnoCSS with one line of CDN import.
- [VS Code extension](https://marketplace.visualstudio.com/items?itemName=antfu.unocss)
- Code-splitting for CSS - ships minimal CSS for MPA.
