Div/Iframe will not expand/envelop child obj

[Nago]

Since the layout is a mite sloppy, I'll start with a link to a testing page with a similar layout- the 'real' one has a chance to contain offensive material.This test page is a static, dumbed down version of the real page, but should allow me to fix my 'real' page if this one can be fixed.http://trimex.us/test.shtmlThe problem is this: I use several div elements to align various things, mostly due to my incomprehension of html and css- div class main, which encompasses nearly the whole page, div class con, which stands for container, which encompasses most relevent text in the 'body' target area of the site- you'll see when you click the link.the Iframe in this was meant to span 100% of the visible width and height, which obviously presents some problems if the menu decides to scroll any, but let's just say the height for this window should be maintained at 90% of the total screen height. (this would prevent it from scrolling out of sight if the menu got very long.)Anyway, the problem is that the iframe in firefox (and most browsers) is appearing as a very thin...thingy. css sheet being loaded can be looked at here...http://trimex.us/var/trimex.cssand, oh. the thing being loaded in that frame is Webcit, an httpd frontend for the citadel bbs software- it would be impossible to have it appear in the page normally, outside of an iframe, or any other "load an external website" magic trick.suggestions? it only has to match html4.01 frameset, but I'd like the css to stay as valid as possible (even though it's invalid now ;_

Still can't figure it out. I've oversimplified the HTML and the CSS to try to spot the problem.http://trimex.us/test.shtmlhttp://trimex.us/var/test.cssIf you try to load via MSIE, this will also be loaded:http://trimex.us/var/trimex-ie.cssI've had absolutely zero luck with this. If someone can point me to something that'll help, it'd be really appreciated.

I've found the single items I have to 'remove' to get iframe to be unhindered (as if you were just placing an iframe code in a blank .html file) --A) the line "position:absolute;" from my "main" div in my css, and:) the doctype.Any reason why these two objects would interfere with my use of "height=100%" in firefox?Sorry for spamming, but this is driving me crazy, and I'm trying to provide useful information for each sequential reply. If this is something that simply cannot be solved, a reply telling me so would be useful :|
