Show/Hide components based on screen size

I’m trying to make a view responsive but with no success.
I have a Column based view, and I need to add a Flex container. I need this flex container to Show only on small size screen and hide it on medium and large screens. I can’t find how to do this.

Does any have a clue?

Thanks in advance.

Put it inside a breakpoint container. Nesting containers is key to Perspective layouts.

Great, so if I have more than one breakpoint I should nest more breakpoint views?
