change dimensions of webpage

i have a webpage that looks like this:

http://yoursdproperty.com/index2.php?option=com_jumi&fileid=3&Itemid=11

i want the page to be the same size as the dimensions of the little form on the page.

is there something i can modify in this code of the page?

<div id="mlcalc-w1">
<div id="mlcalc-w2">
<div id="mlcalc-w3">
<div id="mlcalc-w4">
<div id="mlcalc-w5">
<link rel="stylesheet" type="text/css" media="screen,projection" href="http://www.mortgageloan.com/sites/all/themes/mortgageloan/css/tool/mlcalc-inline.css">
<div id="mlcalc-pres">

You could use JavaScript to get the computed height and width of the element that you want to resize to and pass them to the window.resizeTo method.

A simple example:

This code courtesy of Robert Nyman:

function getStyle(oElm, strCssRule){
    var strValue = "";
    if(document.defaultView && document.defaultView.getComputedStyle){
        strValue = document.defaultView.getComputedStyle(oElm, "").getPropertyValue(strCssRule);
    }
    else if(oElm.currentStyle){
        strCssRule = strCssRule.replace(/\-(\w)/g, function (strMatch, p1){
            return p1.toUpperCase();
        });
        strValue = oElm.currentStyle[strCssRule];
    }
    return strValue;
}

Now for my code:

window.onload = function() {
    var element = document.getElementById( 'micalc-calc' );
    var width = getStyle( element, 'width' );
    var height = getStyle( element, 'height' );
    window.resizeTo( parseInt( height ), parseInt( width ) );
};

Its probably worth noting that it's generally considered a good idea not to resize a browser window via JavaScript, or any way after the window is created. The main reason being that someone may have opened the page in a new tab and you're then resizing all their pages. Rather, have the link that opens the window do so with a size set for it.
