What are HTML Comments?

HTML comments are non-visible annotations within the HTML code. They help web developers and designers document their code, making it easier to understand and maintain. Comments are ignored by browsers and do not appear in the rendered webpage.

Comment Syntax

To create a comment in HTML, use the following syntax:

<!-- This is a comment -->

Everything between the <!-- and --> will be treated as a comment.

Common Uses of HTML Comments

• Documentation: Comments can be used to explain sections of code, making it easier for others (or yourself) to understand the purpose of certain elements.

<!-- This section is for the header -->

• Debugging: Temporarily comment out code to disable it without deleting it, which can help with troubleshooting.

<!-- <p>This paragraph will not be displayed.</p> -->

• Version Control: Comments can be used to note changes or updates in the code, providing a history of modifications.

<!-- Updated the footer on 10/22/2024 -->

• Conditional Statements: When using server-side scripting, comments can clarify logic that might not be immediately apparent.

Best Practices for Using HTML Comments

• Use comments to explain the purpose of complex code or layout choices.
• Keep comments concise and relevant; avoid excessive commenting, which can clutter your code.
• Regularly update comments to reflect current code; outdated comments can be misleading.
• Avoid using comments for sensitive information, as they can be viewed in the page source.
