Sorry, for my bad english.

Bump. curious as to a reply to the post above by bambinovie.
I am looking for something similar.

I’ve added that css provided by Code96 to my theme css, But I still get squished columns when using a mobile device or small browser window.
Am I doing something wrong here?

Thanks.

Nevermind, I solved by unchecking the “Enable Optional CSS” in the plugin settings.
