Trying to use custom classes to modify item attributes from desktop to mobile versions. For instance…class “mobile-mainlogo” applied to the logo image in the mobile view, set to 250px width. Then class “desktop-mainlogo” applied to the same image in desktop view, set to 450px width. However the both classes show up on the image in both views and one class ends up overriding the other.
Did I misunderstand how breakpoints is supposed to work? Thanks in advance!
