Sumi.css：轻量极简的无类CSS框架

Vladimir Carrer在Hacker News上展示了Sumi.css，一个极简的、无类优先设计的CSS框架。1该框架以单文件形式提供，压缩后仅6.7KB，无需JavaScript依赖和构建步骤，开箱即可为语义化HTML元素直接应用样式。1

框架的设计强调易用性和可定制性。所有设计决策均通过CSS自定义属性（--s-前缀）实现，元素样式采用:where()选择器包装以实现零特异性，便于用户覆盖和定制。1Sumi.css默认支持亮暗模式，并可自动跟随系统设置。1该项目采用MIT许可证发布，兼容Chrome 111+、Edge 111+、Firefox 121+和Safari 16.2+等现代浏览器。1

Vladimir Carrer has unveiled Sumi.css, a minimalist CSS framework designed to style semantic HTML elements without requiring classes, build tools, or JavaScript dependencies 1. The entire framework is delivered as a single file compressed to just 6.7 KB, making it immediately usable out of the box 1.

The framework prioritizes simplicity and customization through CSS custom properties prefixed with --s-, allowing developers to easily override default styles 1. All element styling is wrapped in :where() selectors, which provide zero specificity to ensure straightforward style overrides 1. Sumi.css includes built-in support for light and dark modes that automatically adapt to system preferences 1. The project is released under the MIT license and maintains compatibility with Chrome 111+, Edge 111+, Firefox 121+, and Safari 16.2+ 1.
