Ignore part of a template.

Everything inside a {% comment %} block is not output.


This will show.
{% comment %} And this will not show {% endcomment %}

This will output:

This will show.

An alternative to the {% comment %} tag is to use the {# ... #} construct:

This will show. {# And this will not show #}

The big advantage of this notation is that the contents of the {# ... #} construct don’t need to be grammatically correct, as they will not be parsed. The contents of a {% comment %} block must be correct as they will be parsed by the template compiler.
