Divi – Remove the divider line between content and sidebar

By default the Divi Theme displays a dividing line between the main content and the sidebar. It’s possible to remove this dividing line using CSS.
Note that there are two cases in which a dividing line may occur (either on a standard sidebar, or on a sidebar module).
