What are common causes?

Forgotten closing tag on a container. Self-closing assumptions (` ` vs XML-style ` `) depending on parser. Paste-in content breaking the template structure.

Use your editor’s bracket matching from the opening tag downward. Run the HTML validator and fix errors from top to bottom — earlier fixes often remove later noise.

A missing `</div>` (or wrong order of closes) shifts the whole DOM tree. Validators point near the first token that cannot be reconciled.
