Setup

var myDiv = document.getElementById('myDiv');
  var $myDiv = $(myDiv);
  
  // getComputedStyle isn't compatible with all older browsers (notably IE),
  // so this is a wrapper function that works with those browsers.
  // From http://www.quirksmode.org/dom/getstyles.html
  function getStyle(el, styleProp) {
    if (el.currentStyle)
      var y = el.currentStyle[styleProp];
    else if (window.getComputedStyle)
      var y = document.defaultView.getComputedStyle(el,null).getPropertyValue(styleProp);
    return y;
  }
