1. Introduction to HTML Comments

HTML comments are non-rendered text that provide notes within your code. They help you and other developers understand the purpose and structure of your web page.

2. Why Use HTML Comments?

Comments serve various purposes:

  • Documenting code for yourself and others
  • Providing context to complex or unconventional solutions
  • Temporarily disabling code during troubleshooting

3. Syntax of HTML Comments

HTML comments are enclosed between <!-- and -->:

<!-- This is a comment -->

4. Examples of HTML Comments

Comments can be added to any part of your HTML code:

<p>This is a regular paragraph.</p> <!-- <p>This is a commented-out paragraph.</p> -->

5. Best Practices for Using HTML Comments

  • Be concise and clear in your comments.
  • Avoid over-commenting; focus on essential explanations.
  • Use comments consistently for better collaboration.

6. Commenting Out Code

Comments are also useful for temporarily disabling code:

 
<!--<p>This paragraph won't display.</p>-->

7. Accessibility Considerations

Ensure comments do not affect accessibility. Screen readers may interpret comments, affecting user experience.

8. A Practical Example: Commenting for Clarity

 
<!DOCTYPE html>
<html>

<head>
    <title>Commenting Example</title>
</head>

<body> <!-- Header Section -->
    <header>
        <h1>Welcome to Our Website</h1>
    </header> <!-- Main Content -->
    <main>
        <section>
            <h2>About Us</h2>
            <p>This section contains information about our company.</p>
        </section>
        <!-- Commented-Out Section <section> <h2>Services</h2> <p>This section showcases our services.</p> </section> -->
        <section>
            <h2>Contact</h2>
            <p>Contact us for more information.</p>
        </section>
    </main> <!-- Footer Section -->
    <footer>
        <p>&copy; 20XX YourCompany. All rights reserved.</p>
    </footer>
</body>
