A question on frames.
 

I want to make a part of the site non-refreshing, like for a music player which would continue even if the page is switched. I am guessing the only way to do this is with frames, however I've heard many bad things about frames. What is an 'iframe', and is there a better way of doing this?

To do what you want, you'll probably have to use a frame (not iframe) or a popup window (ugh) to do it. Unless you want to code the whole site in flash or javascript, which would not be a good idea.
