GoKawiilFCSS 2 launches as utility CSS library using literal CSS property names
FCSS 2 is a utility CSS library where each class name maps directly to a CSS property and value, such as padding--24 for padding: 24px, removing the need for a separate naming convention. It supports hover, ARIA and breakpoint variants within class names, outputs plain CSS with no runtime, and relies on a build step to purge unused classes. It currently integrates with Vite, Next.js, Astro and Angular, requires Node.js 20.19+ or Bun, and does not yet scan Vue or Svelte files for class usage.
