HTML comments within comments?
Is there a way to comment multiple lines... which already have some comments in them?
i.e.
will always end the comment section so if your comment includes a comment the closing tag of your included comment will end the comment section.
You can do a replace of --> in the section you are about to comment out to something unique so you can later just do another replace back to --> if you choose to undo your commenting.

Nope, unfortunately HTML comments don't nest.
No. Comments cannot be nested and HTML has only one style of comment.
it may still be useful for some developers, if use use vsCode as your IDE you can use an extension named Nest Comments in visual studio code market which work like a charm.
this is the link Nest Comments
I think the key point is this:
Note that comments are markup.
http://www.w3.org/TR/html4/intro/sgmltut.html#h-3.2.4
This is not valid markup:
<div <span/> />
... so neither is the one you mention.
Since all my sites are written in PHP I normally comment out code with PHP comments:
<?/*?>
<div>...</div>
<p>...</p>
<?*/?>
Perhaps you can use a similar trick.
If you're really stuck with some piece of HTML – pre-rendered at some uncontrollable source – which contains comments, and you need to make sure none of it is rendered on your page, you can always wrap it with a script tag like below, only thing is, you can't comment out script tags this way.
<html>
<head>
</head>
<body>
<!-- multiline "comment" below using script type="text/html" -->
<script type="text/html">
Hello world!
<!-- Look at me, I'm a comment :) -->
<div>Yeah, whatever, I'm an element..</div>
</script>
<span>Who cares, span is the man, the only visible one anyway!</span>
</body>
</html>If you need to comment out script tags, you could use a textarea as wrapper instead, off course doing it this way, you can't comment out textarea tags.
<html>
<head>
</head>
<body>
<!-- multiline "comment" below using textarea style="display:none;" -->
<textarea style="display:none;">
<script>
alert("which won't show up..");
</script>
Hello world!
<!-- Look at me, I'm a comment :) -->
<div>Yeah, whatever, I'm an element..</div>
</textarea>
<span>Who cares, span is the man, the only visible one anyway!</span>
</body>
