title: jQuery increase height by 10px without selecting element twice
body: <p>I want to increase my selected elements height by 10px. Is there a better way without selecting the element twice. </p>
  
  <p>E.g</p>
  
  <pre><code>$(this).height($(this).height()+10);
  </code></pre>
  
  <p>Is there some method in jquery which handles this that I have missed?</p>
