title: How to apply background images as thumbnails in bxslider pager?
body: <p>I am using bxslider, thumbnails as pager. The functionality works well, but I can't seem to apply background images to the thumbnails. Anyone knows why? HTML and CSS are below. </p>
  
  <pre><code>&lt;div class="thumbs"&gt;
    &lt;a href=""&gt;&lt;/a&gt;
    &lt;a href=""&gt;&lt;/a&gt;
    &lt;a href=""&gt;&lt;/a&gt;
    &lt;a href=""&gt;&lt;/a&gt;
  &lt;/div&gt;   
  
    .thumbs a {
      display:block;
      width:150px;
      height:100px;
  
      float:left;
      background-image:url('images/m2g_logo.png');
  }
  </code></pre>
