  <ul>
    <li>One</li>
    <li>Two</li>
  </ul>
</div>

💡 Proper nesting and indentation applied

Mixed Inline/Block

<p>Hello <strong>World</strong></p>
<p>Hello <strong>World</strong></p>

💡 Inline elements stay on same line

Common Mistakes to Avoid

⚠️

Over-indenting inline elements

Solution: <span> and other inline elements should stay on same line as surrounding text for proper rendering.

⚠️

Ignoring HTML5 optional tags

Solution: HTML5 allows omitting </li>, </p> in some cases. Beautifier may add them back. Know your doctype.

⚠️

Breaking JavaScript in attributes

Solution: Inline event handlers like onclick may be reformatted incorrectly. Move JS to external files instead.
