How is it guaranteed to comment out any piece of HTML?

Question

HTML

Good afternoon habra community!

An interesting, and as it turned out, non-trivial question arose. It is necessary to insert lines in the html text in such a way that an arbitrary block with any valid content can be commented out.

Option 1. Write naturally:

<!-- 

тут наш код для отключения

-->

And immediately a bummer: It is allowed to add other tags inside the comment, nested comments (when one comment is located inside another) are not allowed .

Our comment is broken by any nested comment (check it out for yourself)!

Next I found a wonderful tag

<comment> </comment>

It turned out that it is only supported by IE, so I didn’t even look at how it works.

The last idea was:

<script type="text/javascript"> /*

тут наш код для отключения

*/ </script>

Almost exactly what you need ... until the first nested script! If it is inside, then everything after the closing tag is uncommented.

What way do you know?

Answer 1

I would
advise you to cut the required piece of code and paste it into another file with the same name. file.

Answer 2

<?php /*
комментарий
*/?>
well as an option)

Answer 3

comment
I don’t even know, I was puzzled by the question =)

Answer 4

In the long run, it makes sense to abandon the software system that forces you to face such tasks.

Answer 5

If this option is suitable, then you can add script tags:

<script> 
/* разметка */ 
// или так
</script>

Answer 6

So far I see the only option: jsfiddle.net/6Xr2w/1/
1. Comment inside the script with single-line comments
2. For nested </script> tags, replace brackets with < and >
3. Wrap the script of the first level in <![CDATA[...]]>, for validity =)

Answer 7

friends, how are you?
<?php /*
comment
*/?> the
first options also do not work
with display: none - in general, a risk

Answer 8

<!-- Коммент ВРЕМЕННЫЙ

<! Коммент постоянный 1 >
<div class="a">
  <p>Lorem ipsum dolor sit, amet.</p>
</div>

<! Коммент постоянный 2 >
<div class="b">
  <p>Lorem ipsum dolor sit amet.</p>
</div>	

<! Коммент постоянный N >
<div class="c">
  <p>Lorem ipsum dolor sit amet.</p>
</div>

Here I googled it. I just started, in the sense of a beginner, so I did not check in all browsers, only in Chrome. I don’t know if such comments will pass validation, because I heard about validation, but didn’t google it;) But sublime syntax highlighting even adequately displays such comments.
