Yes! You can add comments any where in the HTML code.

<!-- This is under comment -->

edit:- you can't use inside tags and inside comment itself.

Answer 2

Yes u can add anywhere
But not inside tags and inside a comment itself
for example:

<div <!-- hello --> ></div>
not valid

<!-- <!-- -->-->
not valid

Answer 3

Yeah ,but make sure that comments do not nest which means a comment cannot be put inside another comment.
Second the double-dash sequence "--" may not appear inside a comment except as part of the closing --> tag.
You must also make sure that there are no spaces in the start-of comment string.
(for example < !--comment--> is not valid)
