Is it necessary to wrap ul elements in div tags for styling purposes, or can they be used without divs to simplify the code structure?

It is not necessary to wrap ul elements in div tags for styling purposes. You can style ul elements directly using CSS without the need for additional div tags. This can help simplify the code structure and make it more semantic.

<ul style="list-style-type: none; padding: 0;">
  <li>Item 1</li>
  <li>Item 2</li>
  <li>Item 3</li>
</ul>
