How to hide elements on PC

Hello,

I have a question regarding hiding elements in Upfront builder, in PC view... the thing is, that I want to change a layout of the text for example on mobile, but when I change it, it changes also on PC view, so now I have built the site with every element twice and now the question is, how to hide the second one on PC-notebook view. Hiding on mobile works great. But not the other way.
