Fylgja CSS is a modular CSS library built around plain HTML. Pick exactly the parts you need, combine them with the tools you already use, and override anything without fighting specificity.
- Base: classless defaults that make plain HTML look good, kept at zero specificity with
:where. - Tokens: one design language as plain CSS variables, for colors, sizes, shadows, easing and more.
- Utilities: a curated set of utilities you tune with a CSS variable instead of a new class.
- Components: small, single class components such as card, badge, callout and toast.
- UI: components you copy, not dependencies you install. Plain, accessible HTML that works with any framework.
npm install fylgjaThis installs Base, Tokens and Utilities in one go. No build step? Copy a file straight into your project with npx fylgja@latest add base, or link it from a CDN. The getting started guide covers every option.
