after further research using Majid's answer, I found out that Jquery's ".css" method return computed style as well, and is better because it accounts for browser difference http://api.jquery.com/css/

Use computed-style. Here's a simple tutorial: Get Computed Style

And as for jquery, it can help you get a reference to the source and target element and apply the css rule easily. let's say you are only interested in two properties, width and height, then you can use code along the lines of:

var oSource = $('#source');
var sWidth  = document.defaultView.getComputedStyle(oSource, null).width;
var sHeight = document.defaultView.getComputedStyle(oSource, null).height;
$('#target').css('width', sWidth).css('height', sHeight);
