title: Background image not showing up in span tag
body: <p>Im having trouble with a span tag showing a background image in the latest FF on windows 7.
  It seems to work and show everything fine in earlier FF, Chrome, Safari and IE but handheld devices and windows 7 it seems to fail.</p>
  
  <p>Sorry if this seems vague I just cant figure it out, the images were originally pngs with no height specified and ive since made them gifs and applied a height.</p>
  
  <pre><code>&lt;span class="design"&gt;Design Viz&lt;/span&gt;
  &lt;style&gt;
  .design  {
      background:url(_includes/images/agenda-design.gif) no-repeat top left;
      display: inline-block;
      height: 17px;
      padding-left:25px;
  }
  &lt;/style&gt;
  </code></pre>
