  * The #GtkButton widget can hold any valid child widget.  That is, it can hold
  * almost any other standard #GtkWidget.  The most commonly used child is the
  * #GtkLabel.
+ *
+ * # CSS nodes
+ *
+ * GtkButton has a single CSS node with name button. The node will get the
+ * style classes .image-button or .text-button, if the content is just an
+ * image or label, respectively. It may also receive the .flat style class.
+ *
+ * Other style classes that are commonly used with GtkButton include
+ * .suggested-action and .destructive-action.
