title: can we use <span> to hold image file?
body: <p>What is the purpose of the empty <code>&lt;span&gt;</code> in the below code. I always thought <code>&lt;span&gt;</code> was used to style inline elements. However, in the below code it looks like <code>&lt;span&gt;</code> is used to hold the image file? 
  can someone please explain the purpose of the <code>&lt;span&gt;</code> tag here? </p>
  
  <p>thanks in advance! :) </p>
  
  <pre><code>&lt;ul&gt;
  &lt;li&gt;&lt;a href="index.php?id=1" class="selected"&gt;Home&lt;/a&gt;&lt;/li&gt;
  &lt;span&gt;&lt;img src="assets/images/divider.png" /&gt;&lt;/span&gt;
  &lt;/ul&gt;
  </code></pre>
