Is there any way I can make a link that opens up in a little box, almost like an iframe at the bottom of my page? And a bunch of links open up only in that, while keeping the rest of my page where it is? Thanks!

Ok... so you don't want an iframe? I only think that iframes & frames target links like you described, I don't know of anything else that does that...

I agree - the easiest way to do what you propose is to use an iframe.

The linked page can then be set to blend in to your background (e.g. black) with a link.

This link can then move to open up a new page with more links.

Put all of the content in the iframe in a span, div, or table that is of the same size as your iframe to hide the fact that it is an iframe.
Disable borders and scrollbars.
