What CSS3 book, like You don't know JS, should I read?

Question

css

Hello everyone)
I know CSS well, but I feel that there are hidden aspects in it, knowing which, you can significantly increase the skill of deep knowledge of CSS. I mean it has to do with animations, performance and stuff like that. In general, I would like to see the best practices for writing and developing and CSS code. I'm looking for something like "You don't know JS" that might open up new sides of the language. I will be glad if, in addition to CSS books, you will also recommend important books on web development that can provide valuable information. Thank you.
