title: CSS background image without text?
body: <p>I have a simple info icon and I want to display it as css background image. This is what I tried:</p>
  
  <pre><code>span.info {
      background-image: url(info.png);
      float: right;
      width: 17px;
      display: block;
  }
  </code></pre>
  
  <p>This is how I use it: </p>
  
  <pre><code>&lt;span class="info"&gt;&lt;/span&gt;
  </code></pre>
  
  <p>This does not display the image. I have to have some text, like this:</p>
  
  <pre><code>&lt;span class="info"&gt;test&lt;/span&gt;
  </code></pre>
  
  <p>This displays the image with text, but I want it without any text, just the image. Whats wrong?</p>
  
  <p>Thanks!</p>
