dev.css is a tiny, simple, classless CSS framework inspired by Vercel's Geist design system. It is designed to make any plain HTML file look clean and modern. The minified stylesheet weighs only ~5.5kb and includes both light and dark themes. Want a demo? See Demo.

For installation instructions and much more information, see the README.

Who is this for?

dev.css is a great choice for:

• A simple blog
• A simple "about me" website
• Collecting your most used links
• Prototyping your raw HTML

dev.css was not meant for very complex websites. An example of a site that uses dev.css is SkywardMC's wiki. This website was also entirely made with dev.css, of course.
