title: Background not appearing for some webpages
body: <p>The background is appearing for some of my webpages and not for some.</p>
  
  <p>This is my main.css:</p>
  
  <pre class="lang-css prettyprint-override"><code>html {
      background: url("../images/bg.png") no-repeat center center fixed;
  }
  </code></pre>
  
  <p>I notice webpages with single path eg. <code>localhost:8080/index</code> will have the background but double path eg. <code>localhost:8080/index/register</code> will not have the background.</p>
  
  <p>Thanks in advance.</p>
