HTML Comment tags

Comment tags are used to insert comments in the HTML source code.

comments syntax

You can add comments to your HTML source by using the following syntax:
<!-- Write your comments here -->
Notice that there is an exclamation point (!) in the opening tag, but not in the closing tag.
Note: The link's destination is specified in the href attribute.

Example

With comments you can place notifications and reminders in your HTML :
<!-- This is a comment -->
<p>This is a paragraph.</p>
<!-- Remember to add more information here -->

Example

Comments are also great for debugging HTML, because you can comment out HTML lines of code, one at a time, to search for errors:
<!-- Do not display this at the moment
<img border="0" src="pic_mountain.jpg" alt="Mountain">
-->

Conditional Comments

You might stumble upon conditional comments in HTML:
<!--[if IE 8]>
    .... some HTML here ....
<![endif]-->

Software Program Tags

HTML comments tags can also be generated by various HTML software programs.
For example <!--webbot bot--> tags wrapped inside HTML comments by FrontPage and Expression Web.
As a rule, let these tags stay, to help support the software that created them.
