Are nested HTML comments possible?

Question

Hello, as per the title; is it possible to have nested comments in valid HTML? see the example below...

<p>some text</p>

  <!-- comment 1

    <p>commented out html</p>

    <!-- comment 2

      // are nested html comment allowed?

    end of comment 2 -->

    <p>more commented out html</p>

  end of comment 1 -->

<p>some more text</p>

It appears not, does anybody know how I could get nested comments to work?

Thanks in advance.

Answer 1

It cannot be done... --> will allways end an existing html comment

Answer 2

When you nest a comment, replace "--" with "- -". When you un-nest, reverse the procedure. It's not the <!-- that is forbidden but the --.

Answer 3

Some editors have commenting/uncommenting commands which can automatically handle existing comments in a block of text. Visual Studio e.g. is doing that when you press Ctrl+KC and Ctrl+KU.

Answer 4

I think it isn't allowed, but as far as I know it works in most of the major browsers except in Firefox.

Answer 5

try using this

<!--

this is the start of the comment

<%-- this is another comment --%>

<%-- this is another one --%>

--> end of the comments
