⭐️ Experimental CSSWG drafts index page was slightly refactored recently. It's page got a dark theme and is now automatically updated once a day. Feedback is highly appreciated! csstree.github.io/csswg-drafts-i…

⭐️ Finally, CSSTree has been updated to 1.0 on astexplorer.net (astexplorer.net/#/gist/4a910fb…). It also has settings now! Kudos to Sergey Melyukov 🙏 (PR: github.com/fkling/astexpl…)

CSSTree v2’s tokenizer is the absolute fastest, with a comfortable lead, and the semantically correct number of tokens. Roman Dvornov even fixed tests that inaccurately benchmarked CSSTree v1. Thank you, from the web. github.com/csstools/token…

Looks like CSSTree's definition syntax matching with an appropriate dictionary could be used for SVG attribute validation:
