Let FF and IE stay closer

Added IE proprietary properties and methods to FF:

For example, use Currentstyle in FF

<! DOCTYPE HTML PUBLIC "-//W3C//DTD XHTML 1.0 transitional//en" "Http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd ">
<style type= "Text/css" >
#a {width:100px;height:100px;background-color:yellow;}
</style>
<script type= "Text/javascript" >
Window.onload=function () {
htmlelement.prototype.__definegetter__ ("Currentstyle", function () {return This.ownerDocument.defaultView.getComputedStyle (this,null);});
The preceding line of code adds the Currentstyle attribute to all HTML elements
var A=document.getelementbyid ("a");
Alert ("Width=\ in Style", "+a.style.width+" \ \tcurrentstyle width=\ "" +a.currentstyle.width+ "\");
}
</script>
<div id= "a" ></div>
</body>
