What bothers me is that I saw many of these things implemented in CSS only in ~2004. Of course, it required much more code then, including shims for IE 6 and careful slicing of GIFs, but things like tabs, accordion or lightbox were being implemented. Makes me wonder where the last decade went. At least there was a good reason to avoid JS back then: it was slow and often looked worse than CSS hacks.
