What is CSS?

CSS = Cascading Style Sheets. CSS consists of instructions that can be applied to nearly every web page element--that control the way the element looks and behaves. You could, for example, instruct a page to always display boxes around links in green with a dotted border if you wish, and do it in only a few lines of code. You can make all text in a page be a certain font-face, yet have different font-sizes at different places.

I've heard a lot of people say that CSS is a pain in the neck but I seem to like it for some reason. CSS stands for Cascading Style Sheets. CSS makes it possible and easier to have a uniform graphic format for a website.
