The instant on-demand Atomic CSS engine.

for the story behind

Fully customizable - 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 - aliasing utilities, dynamically.
Attributify mode - group utilities in attributes.
Pure CSS Icons - use any icon as a single class.
Variant Groups - shorthand for group utils with common prefixes.
CSS Directives - reuse utils in CSS with @apply directive.
Compilation mode - synthesizes multiple classes into one at build time.
Inspector - inspect and debug interactively.
CSS-in-JS Runtime build - use UnoCSS with one line of CDN import.
VS Code extension
Code-splitting for CSS - ships minimal CSS for MPA.
