HTML Comments

Comments are used to explain parts of an HTML page. They help to understand the code and increase its readability. It is also used to test parts of its code to temporally exclude them instead of having to delete them.

The tag begins with an exclamation mark but is not present at the end.

Note : Browsers ignore this tag and therefore do not display its content to visitors to the html page.

Example :

<p>This is the visible part of the article.</p>
<!--  Welcome to the amiradata ! Comment the article :) -->
