Always On Top Content Script

[Aggie]

Hi,

This is about the Always on top Content (IE5) script at

http://www.dynamicdrive.com/dynamicindex11/topcontent.htm

I don't really know much about DHTML, but I would like to use a script similar to the Always on Top one. There is something like it at:

http://www.geocities.com/Heartland/Plains/6271/compquip.html

(with the Yahoo ads in it).

The main difference being that it has different images shown for opening and closing (the little arrows).

I have 2 questions - one, is it possible to have something like this that would work in all browsers and not just IE, and two, what would you call that kind of thing? A popup? A content window?

Thanks!

Aggie
