It's probably not for everyone but I just read the specification [1] last week. It is probably also worth noting that I did this to get a better understanding of some details and not for initially learning CSS. But those are mostly easy to read specifications and I think one could use them to initially learn CSS.

CSS level 1 is pretty short but will still teach you a big chunk of the fundamentals of current CSS even though it is more than 20 years old. After that you can focus on the changes and additions in later versions - those newer specifications are a lot more technical and precise and cover a lot more features, so they are also longer and less fun to read from cover to cover.

I commend you. I am with Kyle Simpson (of the You Don't Know JavaScript fame) here—too often people don't even try to learn about the stuff they are using and are surprised by the behaviour which is clearly stated in the specification. This is true for JavaScript, but this is especially true for CSS. I think it is one of the least respected technology, devs don't spend much time and effort in learning it and then complain about it being a mess and not making sense. So if anyone is tired at throwing stuff at the wall and seeing what sticks just go and read the specs. It's much easier now than back in the days of IE5/6, no grid and no flexbox.

That was brave. I learned how the box model works from the specification.
