Grid system in Astra theme

Hi,

I have a question based on the grid system in Astra. I need to create the custom post type template and it needs to use the grid system.

I can use .ast-container and .ast-row classes on the template. But I can not use the .ast-col-md-4, .ast-col-md-8, and other column classes. It seems the columns classes do not load on the Astra child theme.

I see the .ast-col-md-4, .ast-col-md-8, and other column classes in the “astra/css/minified/style.min.css”.

Is there anyway I can use those column classes in the custom post type template?

Thanks,
Apple
