Which HTML projects are most actively maintained?

What licence are HTML projects usually under?
50 of the 51 carry an explicit open-source licence across 11 distinct licences, and the licence is shown on every card. Permissive licences (MIT, Apache-2.0) are the safest default for commercial use; check the copyleft ones individually.
Should I use HTML or TypeScript for my project?
