/* Theming/Style Classes :: theming.ui
*
* GTK+ uses CSS for theming. Style classes can be associated
* with widgets to inform the theme about intended rendering.
*
* This demo shows some common examples where theming features
* of GTK+ are used for certain effects: primary toolbars,
* inline toolbars and linked buttons.
