Nimble.css minimal classless CSS library for great-looking default HTML

Hacker News

Source code: https://github.com/Leftium/nimble.css --- # About https://PicoCSS.com was a great starting point for projects, but there was some friction: - Global styles leaked into other components (like Userfront widgets or @vincjo/datatables) - Too many breakpoints: I just wanted a single breakpoint for phones, otherwise responsive based on content/screen width. - Too many CSS variables polluting dev tools. - No longer maintained: SASS warnings polluting terminal output. - Missing concept of "surfaces." --- I just wanted a classless CSS library that worked well with https://open-props.style . Basically a nicer-looking Open Props Normalize[1]. So I built Nimble.css! (Assisted by Claude.) PicoCSS-inspired aesthetics combined with Open Props curated values.
