Description

The comment element is a non-standard and little-supported element that’s used to add comments to markup. It has just one attribute—data—that points to a web page that provides further information about the comment. Moving forward, this element shouldn’t be used. Instead, use the standard HTML comment syntax of <!-- comment here -->.

Example

Here’s an example of how comment might be used:

<p><strike>The guy is a fool.</strike><comment>I obviously
misunderstood what he was saying at first!</comment> The guy is an
absolute genius. What was I thinking?</p>

Use This for…

This element can be applied to any text content.

All the browsers tested apart from Internet Explorer ignored the comment element in the example HTML above; they rendered the text it contained as shown in Figure 1.

Instead of comment, you should use this approach to create code comments:

<p><strike>The guy is a fool.</strike><!-- I obviously
misunderstood what he was saying at first! --> The guy is an
absolute genius. What was I thinking?</p>
