title: Problems with underlining
body: <p>I am designing a very basic webpage, with basic HTML and CSS.
  So, I have designated a subpage for my "blog":jx-s-potato.glitch.me</p>
  
  <p>On the page,by writing the following code:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;body&gt;
    &lt;h1 id="title1"&gt;&lt;u&gt;The Blog&lt;/u&gt;&lt;/h1&gt;
  &lt;/body&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>I expected "The Blog" to show up with an underline.However, only "The Blo" got underlined. I thought that this was a problem with my browser so I used Safari to view it.The problem remained.</p>
  
  <p>Is there something wrong about my code? Please help!  </p>
