Pico CSS is no longer maintained

Pico CSS, a minimal CSS framework for semantic HTML, is no longer maintained as of October 4, 2026, with v2.1.1 being the final release. The maintainer cited that AI can now generate lightweight, accessible HTML with necessary CSS, reducing the relevance of minimal CSS frameworks, and that modernizing Pico CSS would require a complete rewrite using current web standards. The project repositories have been archived and are now read-only, though the existing npm packages and CDN will remain available, and the MIT-licensed code is available for community forks.
