The comment tag is used to insert comments in the source code. Comments are not meant to be displayed when the webpage is rendered by the web browser. It is a good practice to use comments to add notes to your HTML code. Doing so can help you when you edit the source code at a later time.

<!--, and to end the comment you use the following sequence of characters:
-->, such as in this

<!--, end with
--> and do not contain
> within the comment.
