I'm trying to create a responsive banner for my website using GWD (728x90). I selected "Match viewports" in the publish size menu and preselected all my position in %. But now my banner uses all the size of my screen and is not 728x90 anymore.
Can somebody tell me how to make a 728x90 (for desktop screen) responsive (for phones and tablets).
