How do I make this iframe extend to the gray area, but show the title at the top? Here is my website to understand what I’m talking about: http://bloggingnetworkonline.com/InternetMarketing/landing-page/

Also, here is the iframe:

<!DOCTYPE HTML>
<html>
<head>
<meta charset="utf-8">
<title>Untitled Document</title>
</head>
<body>
<iframe style="position:fixed;left:0;top:0;
right:0;bottom:0;overflow:auto;width:100%;height:100%; name="myFrame" frameborder="0"src="http://landingpagejosephl.weebly.com/"> 
</body>
</html>
