HTML Comment Tags

You can add comments to your HTML source by using the following syntax:

<!-- Write your comments here -->

Comments are not displayed by the browser, but they can help document your HTML.

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 -->

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]-->

Conditional comments defines HTML tags to be executed by Internet Explorer only.

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.
