title: can jQuery get the size of a dynamic element that has not been drawn
body: <p>What i mean is if i create a Element with jQuery and DOM</p>
  
  <pre><code>var MainHolder = $(document.createElement("div")).addClass("box");
  </code></pre>
  
  <p>if i was to call <code>MainHolder.width()</code> without drawing the element in the window would it be cleaver and work out that it gets the width from the <code>.box</code> CSS class or would it just return 0 as it's not drawn so it can't work it out?</p>
