We add list items to a nested list the same way we add them to other lists.

Add these list items to the nested list.

<html>
<body>
<ul>
<li>Best Comic Book Movies:
<ol>
<li>The Dark Knight</li>
<li>Spider-Man 2</li>
</ol>
</li>
</ul>
</body>
</html>]]>

Make sure to place list item text between the <li> and </li> tags.
