Tailwind CSS is free and funded by extras like Tailwind Plus.

HTML and CSS are free to use but the W3C is funded by membership fees.

Which of those are evolving at the rate of frameworks?

BTW I'm of the opinion that frontend tooling developers should actually try to contribute things to HTML and CSS instead of building "component libraries" on top of them.

If the native controls were good and if the browsers allowed using "uniformly styled" versions of them then there would be no good reason for such libraries to exist.

Your comments in this thread are terrible, all of them. You are part of the reason why working on open source projects is so hard for people who obviously want to do good in this world. Check Adam's work: his work has been a net positive for the OSS community. Go spread your poison and nasty comments elsewhere please.

eeeh.. those are standards, not products.
