title: FA Icon Glow / Shadow
body: <p>Is there some way I can create an icon "glow" effect on a font-awesome icon?</p>
  
  <p>I have tried the following:</p>
  
  <pre><code>&lt;i class="icon-thumbs-down glow"/&gt;
  </code></pre>
  
  <p>and</p>
  
  <pre><code>.glow { box-shadow: 0px 0px 5px #fff; }
  </code></pre>
  
  <p>Unfortunately this results in a "square" white glow around the bounding box of the icon. How can I make a glow that contours to the shape of the icon?</p>
