So I have an app where things are set to a specific size without responsive features, which wouldn’t work with my app. But some thing change the color of the background of my app and this is noticeable on larger screens with white borders. Is it possible to just set the background of a page as responsive so the color stretches to the edges?
You’d put ALL your other content into a main container group, and have that group be fixed with. Then, mark the page as responsive and the color should fill.
