Are nested HTML comments possible?

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?

Solution

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

    Example:

    <!-- some stuff
<!- - some inner stuff - ->
<!- - a sibling - ->
the footer -->
