title: CSS: How to vertically align elements inside div with display: table-cell
body: <p>I want to vertically align two buttons and a span inside a div. The div has:</p>
  
  <pre><code>display: table-cell
  </code></pre>
  
  <p>I have no idea how to do it. I have this <a href="http://jsfiddle.net/xbkr17xn/" rel="nofollow">Fiddle</a> and as you 
  can see the elements are aligned horizontally. I need them to 
  be aligned vertically.</p>
  
  <p>How can i do that?</p>
