I need to make an inline pop-up on my site "zoom out" so that the contents of the pop-up are scaled to the screen size instead of having scroll bars.

This is my code to make the in-line pop-up:
Code:
<html>
<head>
<title></title>
</head>
<body>
<script>
var dragapproved=true
var minrestore=0
var initialwidth,initialheight
var ie5=document.all&&document.getElementById
var ns6=document.getElementById&&!document.all
function drag_drop(e){
if (ie5&&dragapproved&&event.button==1){
document.getElementById("dwindow").style.left=tempx+event.clientX-offsetx
document.getElementById("dwindow").style.top=tempy+event.clientY-offsety
}
else if (ns6&&dragapproved){
document.getElementById("dwindow").style.left=tempx+e.clientX-offsetx
document.getElementById("dwindow").style.top=tempy+e.clientY-offsety
}
}
function initializedrag(e){
offsetx=ie5? event.clientX : e.clientX
offsety=ie5? event.clientY : e.clientY
if (ie5)
document.getElementById("saver").style.display=''
tempx=parseInt(document.getElementById("dwindow").style.left)
tempy=parseInt(document.getElementById("dwindow").style.top)
dragapproved=true
document.onmousemove=drag_drop
}
function loadwindow2(url){
width = screen.width;
height = screen.height;
if (!ie5&&!ns6)
window.open(url,"","width=width,height=height,scrollbars=1")
else{
document.getElementById("dwindow").style.display=''
document.getElementById("dwindow").style.width=initialwidth=width/1
document.getElementById("dwindow").style.height=initialheight=height/1
document.getElementById("dwindow").style.left=5
document.getElementById("dwindow").style.top=ns6? window.pageYOffset*1+30 : document.body.scrollTop*1+30
document.getElementById("cframe").src=url
}
}
function maximize(){
if (minrestore==0){
minrestore=1 //maximize window
document.getElementById("maxname").setAttribute("src","http://site_link/restore.gif")
document.getElementById("dwindow").style.width=ns6? window.innerWidth-30 : document.body.clientWidth
document.getElementById("dwindow").style.height=ns6? window.innerHeight-30 : document.body.clientHeight
}
else{
minrestore=0 //restore window
document.getElementById("maxname").setAttribute("src","http://ka-w3.tw-family.us/js/img/max.gif")
document.getElementById("dwindow").style.width=initialwidth
document.getElementById("dwindow").style.height=initialheight
}
document.getElementById("dwindow").style.left=ns6? window.pageXOffset : document.body.scrollLeft
document.getElementById("dwindow").style.top=ns6? window.pageYOffset : document.body.scrollTop
}
function closeit(){
document.getElementById("dwindow").style.display="none"
}
if (ie5||ns6)
document.onmouseup=new Function("dragapproved=true;document.onmousemove=null;document.getElementById('saver').style.display='none'")
</script>
<div id="dwindow" style="position:absolute;background-color:#black; cursor:hand; left:0px;top:0px; display:none" onMousedown="initializedrag(event)" onMouseup="stopdrag()" onSelectStart="return false">
<div align="right" style="background-color:black color:white">
<img src="http://site_link/max.gif" id="maxname" onClick="maximize()">
<img src="http://site_link/close.gif" onClick="closeit()">
</div>
<div id="dwindowcontent" style="height:100%">
<iframe id="cframe" src="" width=width height=height></iframe>
</div>
</div>
<form><input type="button" onClick="loadwindow2('http://site_link.html')" value="Load Map"></form>
</body>
</html>
The pop-up has content from some of my other sites in iframes.
