Maybe I'm misinterpreting but I assumed the subreddit would be a collection of answers like this instead of a place to ask them which would be super cool and helpful. Not sure if that's what's meant though.
for my part, i wonder if these guys with the deep chi on css are probably .. correct me if i'm wrong .. using the source? i.e. do you get some sort of insight by observing how css is handled, in some source somewhere, or .. how ?
No, they just have a very thorough understanding of the box model and all the different selectors. There's quite a lot of pieces and they can interact in many ways; some people just have the right mindset to solve that puzzle.
Is there a good advanced css book (or other long-form resource), or do you just have to read specs at this level? I feel like I have "known" CSS reasonably well for quite some time, but have never attained the level of depth it takes to really grok all the ways the puzzle pieces interact with one another.
