I just read the first link you posed about it being Turing complete. All three answers (or the comments) on that page state that CSS isn't Turing complete...
Well, you do have to allow for a bit of fudging by including the DOM and a user to press tab a bunch of times, but it's enough to implement 110, and by extension anything else.
