I'm having some trouble figuring out how to extend an iframe to 100% of it's container element in Firefox and IE (it works fine in Chrome). From searching around, it makes sense that there has to be a width specified on the containing div (and possibly body and html as well). However, I have done that, and the iframe is still not extending. Do all of the parent divs have to have a specified width and position for this to work, or just the containing parent? Any fix for this would be greatly appreciated!
Here's what I have:
<!DOCTYPE html>
<html>
<head>
<style>
html, body {margin:0; padding:0; height:100%}
#container {width: 1000px; min-height: 550px; position: relative}
#smallContainer {position:relative} /*no width specified*/
#iframeContainer {height: 100%; position: relative}
#iframe {height: 100%; width: 100%; display: block}
</style>
</head>
<body>
<div id="container">
<div id="smallContainer">
<div id="iframeContainer">
<iframe id="iframe" src="foo.com"></iframe>
</div>
</div>
</div>
</body>
</html>
