That's what I've found too. The value of a css framework comes from showing you a structured way to achieve certain things, eg grid based design, font scaling.

That's what I've found too. The value of a css framework comes from showing you a structured way to achieve certain things, eg grid based design, font scaling. Once you know how to do that, you don't need the framework and it's probably just as easy to write the css directly. I've found the best way to use them is a starting point. By the time your site goes live you've stripped out the rules you don't need and customised the names of the classes etc so you can't see much of the original framework.
