* @Short_description: A centering container
* @Title: GtkCenterBox
* @See_also: #GtkBox
*
* The GtkCenterBox widget arranges three children in a horizontal
* or vertical arrangement, keeping the middle child centered as well
* as possible.
*
* To add children to GtkCenterBox, use gtk_center_box_set_start_widget(),
* gtk_center_box_set_center_widget() and gtk_center_box_set_end_widget().
*
* # CSS nodes
*
* GtkCenterBox uses a single CSS node with name box.
*
* In horizontal orientation, the nodes of the children are always arranged
* from left to right. So :first-child will always select the leftmost child,
* regardless of text direction.
*
* In vertical orientation, the are arranged from top to bottom.
