I understand this perfectly and is maybe the argument I have the most sympathy for.

And, because you are absolutely right, I'm working right now on something like what you propose.

The only way to convince people that CSS is a better (as in lighter, simpler, more efficient, etc.) solution than a framework like this, is to show and prove that it is. Arguments can only go so far...

So, as the saying goes, I'll be putting my money where my mouth is. Hehe.
