Is there a way to hide or show an element according to the screen size?

Thank you for your answer.

I was thinking about this way and I have even so this solution from the forum to use to redirect the users: Mfork - Serve different pages depending of your user's devices - #2 by anon78309838
Before to go like that I wanted to know if maybe there is a solution to use only 1 web app and do some changes for components and layout.

Thank you, again!
