Random JavaScript: 100% Height IFRAME
Place the following code just below the IFRAME closing tag to make it auto-adjust to the height of the page.
<iframe id="resizediframe" src="ENTER A URL HERE " width="100%" frameborder="0" marginheight="0" marginwidth="0"></iframe>
<script type="text/javascript">
function resizeIframe() {
var height = document.documentElement.clientHeight;
height -= document.getElementById('resizediframe').offsetTop;
height -= 45;
document.getElementById('resizediframe').style.height = height +"px";
};
document.getElementById('resizediframe').onload = resizeIframe;
window.onresize = resizeIframe;
</script>
