title: How to make a message show up when mouse over icon
body: <p>I am displaying an icon this way:</p>
  
  <pre><code>&lt;?php echo anchor('stuff/edit', '&lt;i class="icon-edit icon-white"&gt;&lt;/i&gt;', array('class'=&gt;'btn btn-info')); ?&gt;
  </code></pre>
  
  <p>And what I want is that when I hover over the icon with the mouse a message that says "Edit" pops up. Just like with the icons on this board, if you hover over the {} icon a message that says "Code Sample..." shows up. I want that using bootstrap.</p>
  
  <p>Thanks in advance.</p>
