Sumi.css - Minimalist classless-first CSS framework in 6.7 KB

Show HN: Sumi.css – CSS Framework

Sumi.css is a tiny, dependency-free CSS framework that styles plain, semantic HTML so your pages look finished without writing a single class. At just 6.7 KB minified and gzipped, it ships as one file with no build step or JavaScript, yet covers headings, forms, tables, cards, accordions, modals, and navigation out of the box. It follows the visitor's system light/dark preference automatically, exposes every color, font, size, and radius as a CSS custom property for easy theming, and uses zero-specificity selectors so your own styles always win without !important. Accessibility touches like visible focus rings, ARIA-driven states, and reduced-motion support round it out. Drop in the CDN link and start writing HTML.
