So I am making changes to the design for portrait mobile, but then the changes are being applied to all devices. The changes are images, grid layout, pagination.
Hi @Auser_using
Thanks for your question about cascading designs.
Only changes in the Styles panel cascade up or down. Any changes on the canvas or in the element settings panel affect all breakpoints (an exception is editing grid on canvas: which opens a popover in the Styles panel where you can directly manipulate on the canvas and changes cascades up and down as necessary)
So, images and pagination settings will affect all breakpoints. Learn more here: Breakpoints | Webflow University
As for the grid layout, what are you changing specifically that’s also changing on larger devices?
