I noticed something that has kinda messed me up unfortunately.
I was on mobile/portrait mode and noted that one of my sections simply would not work for it. So I decided to change it to buttons instead. Looked great but when I went back to desktop, the nice little animated section was now also buttons.
So, here I was thinking that 'changes only go down' but it seems that's only with styles and not whole elements. Meaning if you remove an element while on a mobile design, that element is removed from the desktop as well.
If this is wrong, please let me know what is broken but most likely, my misinterpretation of what 'changes' carried over from desktop down had nothing to do with individual elements themselves.
