Learn how to use comments in HTML to add notes and annotations within your code!

Understanding HTML Comments

HTML comments provide a way to add notes, explanations, or annotations within your HTML code without affecting the appearance or functionality of the webpage. Comments are not displayed in the browser's rendering of the page, making them useful for adding documentation or reminders for yourself or other developers who may work on the code.

Basic Syntax

HTML comments are enclosed within the <!-- and --> delimiters. Anything between these delimiters is considered a comment and is ignored by the browser when rendering the page.

For example:

<!-- This is a comment -->

This comment will not be visible on the webpage, but it provides a note for developers reading the HTML code.


HTML comments can be used for various purposes, including:

  • Documenting code to explain its purpose or functionality.
  • Providing reminders or TODOs for future development tasks.
  • Temporarily disabling or "commenting out" code for debugging or testing purposes.
  • Adding copyright notices or attribution information.

Best Practices

When using HTML comments, consider the following best practices:

  • Be descriptive: Write comments that clearly explain the context or purpose of the code.
  • Avoid over-commenting: Comments should add value to the codebase without cluttering it with unnecessary information.
  • Update comments: Keep comments up-to-date with any changes to the code to ensure their accuracy and relevance.
  • Use comments for documentation: Comments can serve as documentation for your HTML code, helping other developers understand its structure and logic.


Here's an example of HTML comments used to document a section of code:

    This section contains the header of the webpage.
    It includes the site title and navigation menu.
    <h1>My Website</h1>
            <li><a href="#home">Home</a></li>
            <li><a href="#about">About</a></li>
            <li><a href="#contact">Contact</a></li>

In this example, the comments provide information about the purpose of the <header> section, making it easier for developers to understand and maintain the code.


Practice using HTML comments in your code to improve its readability and maintainability. Experiment with different commenting styles and techniques to find what works best for you and your development team.
