Is there anything I can do with Javascript, Div layers, tables, etc. to make an ad in a webpage that you can close (ie: move it waaay off to the left of the webpage) ? Sorry, but I don't know how else to explain. If you understand, please help.

I think what you need are pop-up windows:

What I need is like a <div> layer that comes up in front of my text that has like an "x" button or something that will move it WAAAY off to the left where it can't be seen...

maybe something like chromeless windows??
