The COMMENT Tag

Internet Explorer shipped an element that meant the same thing as an SGML comment.

In 2026: Dead, and it never worked outside Internet Explorer, so anything you put in one was visible to half your visitors. That is the whole story of this tag.

Where it came from: Microsoft Internet Explorer 3 HTML reference, 1996. Wikipedia ↗

<comment>Invisible in Internet Explorer. Plain visible text in Netscape.</comment>

<!-- The version that always worked -->
<!-- Invisible everywhere. -->
