Below I've added code I was able to find that will allow you to make your Div boxes scrollable like an iFrame:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<title>example page</title>
<style type="text/css" media="all">
body {
font-family: Verdana;
font-size: 90%;
}
#scroll_box {
border: 1px solid #ccc;
height: 120px;
width: 400px;
overflow: Auto;
margin: 1em 0;
}
</style>
</head>
<body>
<div id="page">
<h1>Title</h1>
<div id="scroll_box">
<p>
Put a long text in here. It will be scrollable.<br/>

</p>
</div>
<p>
This content follows after the scrollable box.

</div>
</body>
