I'm a web developer, but not a designer, and not hugely proficient in CSS. I understand the basics, but it often takes me a while to get things to look the way I want them. For me, grid frameworks were a revelation - they let me, for the first time, quickly lay out the site with very little pain. Using a framework, I sketch how I'd like the site laid out, and then it's a simple matter of writing a bit of html and adding a few classes to get the layout I want. Working from zero is much harder for me.
