Abstract: " One of the touted benefits of CSS is that it reduces total page weight, and thus download time, both at first page load, and even more on subsequent loads due to style sheet caching. This is true, but often a sizable fraction of the first load savings is lost because of highly redundant CSS code. Well that's all over. Now you will learn some "secrets" of efficient CSS coding, enabling you to pare that style sheet right down to the bare bones. To be sure, you won't achieve huge savings doing this, but for some highly competitive sites every little bit counts."
