Show HN: Sumi.css – CSS Framework

Sumi.css is a minimalist, classless-first CSS framework that styles semantic HTML elements without requiring custom classes, delivered as a single 6.7 KB minified file with no dependencies or build step. It includes built-in support for common components like forms, tables, cards, and modals, along with automatic light/dark mode detection and full accessibility features like focus rings and ARIA support. All styling uses CSS custom properties for easy theming and can be overridden without !important declarations.
