The Importance of Operating Systems in a Web Platform

The operating system was the easy part. So, so the operating system was easy but browsers are hard. And really when it comes to CSS, I would say CSS is so much harder than any of the other parts of the web platform because it's hard to work on any CSS module in isolation like it really requires the person working on CSS stuff to sort of understand multiple specs at the same time and then keep them in their head if that makes sense. It is so much easier to work on JavaScript or HTML or fetch or any of those specs right because they are more self contained.
