title: Extending navigation bar to full width
body: <p>The navigation bar of my website does not extend to the full height of my webpage. I would like to extend it so it fits the page perfectly. Here is my code.</p>
  
  <p><strong>Html:</strong></p>
  
  <pre><code>&lt;div id="Nav"&gt;
  &lt;div id="NavContent"&gt;
      &lt;h1&gt;Header&lt;/h1&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p><strong>CSS:</strong></p>
  
  <pre><code>#Nav {
      width:100%; 
      background-color:#f26522;
  }
  
  #NavContent {
      margin:0 auto;
      width:9999px;
  }
  </code></pre>
  
  <p>How can I fix this issue? Thanks.</p>
