/**
 * SECTION:gtkseparator
 * @Short_description: A separator widget
 * @Title: GtkSeparator
 *
 * GtkSeparator is a horizontal or vertical separator widget, depending on the
 * value of the #GtkOrientable:orientation property, used to group the widgets
 * within a window. It displays a line with a shadow to make it appear sunken
 * into the interface.
 *
 * # CSS nodes
 *
 * GtkSeparator has a single CSS node with name separator. The node
 * gets one of the .horizontal or .vertical style classes.
