Use HTML comments wisely

To make your HTML code clearer for you (and for others), you can add comments to your code. These are snippets of code that are ignored by Web browsers, so they’re useful for adding short notes and reminders within the code:

<!-- Navigation area: Highlight a menu item with the "hi" class -->

<div id="nav">
  <ul>
    <li><a href="/">Home</a></li>
    <li class="hi"><a href="/about/">About</a></li>
  </ul>
</div>
