The W3C have just published a new Design System. It was developed by British Digital Agency Studio 24, who are also working (in the open) on the redesign of the W3C website.
My initial impression is that this Design System feels pretty early-stage and work-in-progress. I’m not completely sold on all of the technical details, however it definitely contains a number of emergent best practices and lots of interesting parts.
I particularly liked the very detailed Forms section which assembles lots of good advice from Adam Silver and GOV.UK, and I also found it interesting and useful that they include a Page Templates section rather than just components and layouts.
It’s cool to see an institution like the W3C have a Design System, and I’m looking forward to seeing how it evolves.
