Split cms images diffrent by devices

HI, I want to create a cms that have 4 columns in the pc and tablet mode, and when it cchanged to mobile mode, I wantt it will be 2 columns.
didn’t find how to do that…

Here is my site Read-Only: LINK

The Column element won’t be of any help for that, but with Flexbox, it’s achievable. To begin with you could set your flex childs at 25% width and get 4 columns, then set them at 50% for devices and get two columns.
