Introduction to <!--comment-->

The <!--comment-->tag is a comment tag in HTML. Any text wrapped inside this tag is ignored by the web browser and does not appear on the page. This feature allows developers to add notes, reminders, or documentation directly within their HTML code without affecting the visual output.
