HTML Comments

HTML comments are used to insert notes or explanations within your HTML code. These comments are not displayed in the web browser but are visible in the HTML source code. They can be useful for documenting code, leaving reminders, or temporarily disabling code during development.

Syntax

The syntax for HTML comments is:

<!-- Your comment goes here -->

Examples

1. Basic Comment

   <!-- This is a comment -->
   <p>This is a paragraph.</p>
   

2. Commenting Out Code

   You can use comments to disable parts of your code temporarily:

   <!-- <p>This paragraph is commented out and will not be displayed.</p> -->
   

3. Documenting Code

   Comments can help explain what specific parts of your code do:

   <!-- This section contains the main navigation menu -->
   <nav>
     <ul>
       <li><a href="#home">Home</a></li>
       <li><a href="#about">About</a></li>
       <li><a href="#contact">Contact</a></li>
     </ul>
   </nav>
   

4. Multi-Line Comments

   You can also use comments to span multiple lines:

   <!--
     This is a multi-line comment.
     It can span several lines.
     Use it for detailed explanations.
   -->
   <footer>
     <p>Footer content here.</p>
   </footer>
   

5. Comments Inside HTML Tags

   You can place comments inside HTML tags, but they should not break the tag structure:

   <div>
     <!-- This is a comment inside a div -->
     <p>Paragraph inside the div.</p>
   </div>
   

Notes

• Avoid using comments to store sensitive information, as anyone with access to the HTML source can see them.
• Be mindful of placing comments in the right place; comments within tags might affect how browsers render the page if not done correctly.
