comment
Ignore part of a template.
Everything inside a {% comment %} block is not output.
Example:
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.
