Breakpoints and responsive formats

Question:
I am having an issue with adjusting my website on other formats such as tablet and phones. Everytime I try to adjust the phone edition, my desktop version also changes.

Product:
Wix Studio

What are you trying to achieve:
Is there a way to adjust all formats according to the desktop version or how can i edit the other versions without affecting the desktop one.

What have you already tried:
I saw that there is an override feature but not sure how to do it.

Namaste,

Which edits are you making? Changes like stack and unstack are reflected across the breakpoints. Use the alignment instead.
