make it so my visitors can choose my sidebar theme... What I want to do is make it so that when vistors want to see the green themed sidebar for example, they click on the green link.Then in the left frame it changes to that theme... kinda like image changing by clicking on a link. Im just not totally sure... i know i can do it one way to where the whole frame changes to another page but I think the image changing way would be easier.

i think you can do that with css. is that what you mean maybe?

I have no idea what it is! SO I put it on the HTML board.
