CSS Style Guides
Improving code readability with CSS styleguides offers some interesting ideas on how to improve your stylesheet readability. In my view, optimisation is about weighing up things like the size and complexity of the stylesheets, who will be reading it, ask whether you need to use redundancy to make things easier to understand, and understanding a lot of small stylesheets means more requests to the server. Its our job to take these ideas and optimise them for our unique projects. Some good ideas here.
