title: Background div not showing
body: <pre><code>&lt;!doctype html&gt;
  &lt;html&gt;
  &lt;style type="text/css"&gt;
  body {
  background-color: #444669;
  }
  #1 {
  background-color: #DD2124;
  height: 337px;
  width: 388px;
  }
  &lt;/style&gt;
  
  &lt;body&gt;
  &lt;div id="1"&gt;&lt;/div&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>I'm trying to make a section of div with a different background color but it doesn't even show at all.</p>
