I uploaded two screenshots, that visualize my problem.
On the first picture (webflow design view):
I want a responsive nav bar, that pushes down other elements, and i built it in design view, it shows it well, and works well it PUSHED DOWN the "plan code success" SECTION, and any others below ...
On the secound picture (preview mode or browsers responsive design view):
IF i switch to preview mode (or in a browsers responsive design view) it OPENS ABOVE MY SECTIONS. (so it displays badly what i made in design view)
I may be not expert in webflow, maybe it is not a bug, but is there or solution to fix this?
