HTML

<h1>The Title
This is a subtitle. Everything looks fine despite above syntax error!
<div>
  <p>As you can see, the author of this page accidentally omitted the <code>&lt;/h1></code> tag from the <code>&lt;h1></code> element. Whoops!</p>
  <p>However, it looks like the Browser has made some guesses about how the page should be rendered, so everything looks good! It goes through code review and everyone gives the thumbs up. Everyone lived happily ever after! <sub><small>&hellip;or did they?</small></sub></p>
</div>
<hr>
<div>
  <p><em>Ominous music.</em></p>
  <blockquote><b>Ticket 3453</b>: Remove subtitle!</blockquote>
  <p>Ah, a new design is in, and you just received a ticket to remove the subtitle. Go ahead and do that by deleting the entire <code>&lt;h2></code> element. Click "Run" to see what happens!</p>
</div>
