The problem is that not all gtk widgets draw their own background. The background is then determined by the underlying widget. This behavior was changed for some widgets with gtk+ 3.12.

So changing the background color of a Gtk.Box does not work for version < gtk+ 3.12. If you are using an older version, an alternative approach would be to use a Gtk.Viewport underneath the Gtk.Box and change the color of the viewport.

To put it into some code:

box = Gtk.Box()
viewport = Gtk.Viewport()
viewport.add(box)
#and the CssProvder, StyleContext,...

CSS:

GtkViewport {
    background-color: red;
)
