Hi all. I hope someone can help me I am making a clickcash site and Im trying to put my sponsors join page (the sign up form) in an iframe on my site and I'm looking for a way make it blend in better to my site and look less "ifriends". I have seen other sites that do this but I don't know how. Here is an example of what I mean.

That looks like her own join page but if you tried to sign up you would see that its actually this form in disguise.

(or look in the source code at the iframe source url and you will see what I mean) 
 
So I was wondering how was this done and can anyone steer me in the right direction? 
 
 
Thanks,
