> Also, just look at that markup. So clean. So shiny.

That’s the essence of so much of this obsessive bit-twiddling: irrelevant aesthetics. The functional aspect of this is a disaster, as others have noted, locking styling to page structure in a way that will require structural changes to the CSS just to move an element on the page.

Yeah. I don’t want to see “wow look at how pretty this markup is”. I want to see “look how flexible and easy to change this is, without redoing everything”.

If you’re not talking about change, the other stuff is pointless.
