That is not the case for me. Without adding any new content, any changes I make in mobile change affect the desktop 100%. If I go to move things around on mobile and then switch back to desktop, my blocks now have increased in height, pushing content further down the page and in some cases WAYYYY down the page adding 20+ rows of blank space to the section. Is there a way to 'lock' what I have done on desktop before making mobile edits?
SquareKicker plugin has laptop and tablet layouts. I read somewhere if you start on mobile and work your way up that would work, but I tried and the same problem occurred in reverse. I am at a loss for what to do!
