No doubt this is a very basic question, but how do you go about creating multiple styles (different styles) for links within the same page? For instance, if you go to www.cnn.com, you can see that they created different links with different ways of doing the rollovers. Some have blue text, rolling over to red with no underline, while others start as white text, rolling over to another color, etc.
Then, how do you go about assigning these values on the web page itself? Did they use multiple css pages? Or are all the values on a single one somewhere?
