HTML Comment tag

Example

An HTML comment:

<!--This is a comment. Comments are not displayed in the browser-->

<p>This is a paragraph.</p>

Definition and Usage

The comment tag is used to insert comments in the source code. Comments are not displayed in the browsers.

It is used to mark some important code or describe its uses to the developer for further edit or any another purposes.

You can use comments to explain your code, which can help you when you edit the source code at a later date. This is especially useful if you have a lot of code.

Tips and Notes

You can use the comment tag to "hide" scripts from browsers without support for scripts (so they don't show them as plain text):

<script type="text/javascript">
<!--
function displayMsg() {
alert("Hello World!")
}
//-->
</script> 

Note: The two forward slashes at the end of comment line (//) is the JavaScript comment symbol. This prevents JavaScript from executing the --> tag.
