It's a bad idea to dynamically add an iframe like that.
Partly because you can't guarantee a user's screen size.
I would advise against absolutely positioning an iFrame anyhow. 
I think it's unreliable unless wrapped in a Div but I've only ever read about doing it.
The way I would approach this is to put the iframe in the hosting page.
Use css styles to make the frame big or tiny.
Change the class name of the iframe using jquery in order to switch between the two states.
You then have a concrete piece of html and css you can work with.
Changing class name:

$("#whatever_id").attr('class', 'newClass');
Hope that helps.
