fuz_css

fuz_css is a CSS framework and design system for semantic HTML. It styles elements by default and integrates custom properties, themes, and utility classes into a complete system. It's Svelte-first but works with plain HTML/JS/TS, React, Preact, Solid, and other JSX frameworks. For more see the framework support docs, and for the companion Svelte components, see fuz_ui.

The only required parts are a reset stylesheet with the semantic defaults and a replaceable theme stylesheet containing the variables used in the reset, and these require no dependencies. There's also utility classes for composition and convenience with a Vite plugin, and the library exports the full API for complex usage.
