I would take a look at BEM. It's methodology and set of naming conventions to help write better, more modular and reusable CSS. It can take a while to get used to, and to get it right, but once you do it's a lifesaver. I can't imagine doing front-end dev without it now
I'm not a designer by any means, so take this with a grain of salt, but after reading through the first link, BEM bears a striking resemblance to hungarian notation, which I think most of us decided was a bad idea a long time ago. Do you have any sense that this naming convention is different somehow from the naming conventions that have been used and abandoned in other areas of software development, and if so, what makes it different?
