How to make a column responsive without affecting the bigger devices

Hi, I’m having trouble with a section of two columns in my design.

I’m trying this animation where one of the columns show three different images throught the scrolling while the other column stays fixed to it side, changing the content with a transition.

But my issue comes when I try to make it responsive in the smaller (mobile) devices, I want to unable this interaction of two columns in the mobile version, and only make it available in the bigger devices, kind of like having one column on mobile devices and two columns in big screen devices.

My question is: ¿Is it possible to do it, or there is no way to make it work in smaller devices?

I’ll leave the read-only link below.
