I have stylesheet block in base layout:
{% stylesheets
filter=\'cssrewrite\'
\'bundles/static/css/main.css\'
%}
Of course, it's possible.
But currently, you don't have stylesheet block. You use the stylesheets tag.
Just add a block like this:
{% block stylesheets %}
{% stylesheets
filter='cssrewrite'
'bundles/static/css/main.css'
%}
<link rel="stylesheet" href="{{ asset_url }}" />
{% endstylesheets %}
{% endblock %}
And in others templates:
{% block stylesheets %}
{{ parent() }}
{% stylesheets
filter='cssrewrite'
'another-css-file'
%}
<link rel="stylesheet" href="{{ asset_url }}" />
{% endstylesheets %}
{% endblock %}
Don't forget to call the parent
function to not override parent stylesheets.
