CSS is very difficult to replace with an abstraction because it's too quirky. Compiling a high level language down to CSS without human intelligence is so difficult, it's completely impractical.

HTML, on the other hand, is easy to abstract. I'm glad I did it in Weblocks, it saves me an enormous amount of time. ASP.NET uses this strategy (use the DataGrid control for a while, and then try coding without it).

JS is somewhere in the middle.
