= CSS Theming/Style Classes

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.
