Fellow EditorX designer and coder here - an issue I run into a ton is that if I make an edit on larger breakpoints, like say a medium-to-large-size laptop, those changes might reflect incredibly poorly on smaller breakpoints, like an iPhone.
My question is: How do I make necessary changes on one breakpoint without damaging branding or U/I on another?
So, EditorX is a cascading editor, meaning the changes you make cascade down to lower breakpoints. What you change on the larges breakpoint will trickle down to the breakpoints below. But changes to smaller breakpoints won’t effect larger breakpoints.
There are a couple of exceptions to this rule, like data changes, or structural changes (reparenting elements etc).
Here’s a couple of links that will hopefully point you in the right direction:
