Homepage and Forum sync or something

[Rage]

I am not really sure how to ask this, but I have a homepage with sidebars, a header with links, and then I have forums. I would like to know how to add an iframe that automatically detects the size of the page and so you don't end up with two scroll bars. If this can be done through CSS, can you let me know how I can do this?

Do you mean that you want the user's resolution settings to be detected, then have your iframe's width/height adjusted based on those settings? For that, you can set the iframe's width/height in percentages, rather than absolute values. But, if you're wanting something more precise (as in you set absolute sizes for each resolution), you'll probably need to develop some javascript.

What I mean is I want the iframe to automatically adjust to the size of the site (forums) so when it expands or reduces in size it will never add extra un-needed space, or reduce it self and cause it to need an iframe scroll bar.
