It is assumed that you have a good working knowledge of HTML already. I'm trying not to offer scripts that are widely available elsewhere. When you use one of my scripts, please either make a copy of the text file provided at the bottom of each tutorial, or drag your mouse over the sample code and copy it that way-- if you copy right from "view source" you will get a lot of unintended code fragments from my own HTML, and you shouldn't be taking that anyway.
