This is really cool. Yet, somehow, as cool as it is, I find it terribly depressing. In comparison to other "look what I can do" projects -- such code golf, or demo programming, or quines -- which achieve impressive results in a constrained environment because it's challenging, thousands of programmers have HAD to do silly things in CSS because there's no other choice. These amazing-yet-hacky solutions get copy-pasted down through the generations and what should be simple becomes enshrined in the arcane. I look at this and become exhausted in empathy.
So in contrast to the opening line of the article, CSS is not amazing: people's talent for threading camels through the eyes of needles is amazing. Props to this guy for this. May I never have to recreate it.
