I'm using firefox w/o javascript... I can see the page, but nothing works yet. All the links are coded to use JS?
Rules of Thumb:
1.) Include doc type, and test in multipule browsers (as many as you have access to).
2.) Never use JS, JAVA, Flash or other technology for navigation or to hold content. If you do, users don't have the plugin or feature turned on can't use your site.
3.) "Frames are bad." Early on, there were a lot of sites that abused frames, by using far too many. This means that they got a reputation for being a "bad" feature to use (even though when used correctly you can make a fairly pretty site). The other pitfall with frames is that text only browsers (both from die hard lynx users and people surfing from moblie devices use), can't see both frames at a time, which means you'd need to provide them a frameless version or they won't be back (nothing for them to see). So, if you use frames, do so thoughtfully and sparingly. I know you didn't, but this post will be looked at later by other starting web designers and it's a good thing to remember.
4.) Don't use absolute positioning. If someone is has a bigger screen and higher resolution, let them use it. If someone has a smaller screen and lower resolution, then don't force them to scroll horizontally. Things like:
should be replaced with percentages... unless you know that most your users are using the same depth/resolution as you.
