Correct cross-browser iFrame format

Hi experts.

I'm using an iFrame to display content from one of my sites onto another site.  Bellow is the code I'm using (the full page).   You'll see I'm using a 100% for width and also a 100% for height so that the iFrame displays "at full" on any computer regardless of what display the person has.  This works great on most browsers except for Firefox. On Firefox it gets the 100% width but it displays no height. I shows only a "little height". I've tried playing with different heights but it doesn't quite work. I'd like to have something that displays correctly on any computer.

How do I need to set up this iFrame so that it displays properly on any browser?

Please help I don't know what elso to try to fix!

Try setting the css style for the iframe element.

ie.
<iframe src="http://www.mysite.com/doc/2009062201/" height="100%" frameborder="0" marginwidth="0" marginheight="0" width="100%" style="height:100%; width:100%"></iframe>

There are a number of height/width related css properties, Im thinking you might be interested in min-height which allows you to set a minimum height for elements. They can grow but not shrink. see http://www.w3schools.com/CSS/pr_dim_min-height.asp

Thanks.

What would you recommend as a minimum height for better browser compatibility? What would work the best? This is what I have.
<iframe src="http://www.mysite.com/2009062201/" height="100%" frameborder="0" marginwidth="0" marginheight="0" width="100%" style="height:100%; width:100%; min-height:730px;"></iframe>

It all depends on your html layout. If you definitely want the iframe to take up the full page (cloaking) then set the width and height to 100%, I only mentioned the min-height to show that their are alot of css features that you might find useful.

Thanks.

Once published and called upon, Firefox gives me an alert message that says:  The page at http://www.mysite.com says: 815 px

What is that?

Should't the iframe adjust to the size of any resolution?

Thanks for the comments.

dont use i-frame
The iframe element is not supported in HTML 4.1 Strict DTD and in XHTML 1.0 Strict DTD.
from
http://www.w3schools.com/TAGS/tag_iframe.asp

use templates to create pages and use proper div based pages instead of iframe's
