<!-- A note that documents the code -->
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.
The comment is not visible, whereas the paragraph is.

<!-- This comment is not visible. -->

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.
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, they allow you to create code-friendly pages.
