HTML Comments

A comment in HTML is text that is marked as documentation. Comments are for developers only and are not visible to the user.

HTML Tutorial

Example

A comment in HTML.

<!-- A note that documents the code -->

Comment Syntax

Comments are added with this syntax:  <!--  . . .   --> .
Anything between <!-- and --> is hidden from the user.

<!-- Insert a comment here -->

Note:  Comments explain the functionality of the code.
This makes it easier to support and maintain the code at a later stage or by another developer.

Comment Example

The comment is not visible, whereas the paragraph is.

This paragraph is visible.

<!-- This comment is not visible. -->
<p>This paragraph is visible.</p>

Tip:  Although HTML comments are not visible on the page, they do appear in the page source.
Therefore, don't include confidential information in your comments.

Tip:  You can also comment large blocks of code, which is referred to as: commenting out the code. Developers commonly use this technique during early page development.


Code Tags

The comment tag is part of a group of tags that create coding (programming) related features on web pages. This group is referred to as the Code tag group. Together, these tags allow you to create code-friendly pages.
