class: AnchorPane

[90:7] extends: Pane

The AnchorPane class wraps the JavaFX AnchorPane layout container, which positions child nodes by anchoring their edges to the edges of the pane. You can anchor any combination of a child's top, bottom, left, and right edges to the corresponding edges of the AnchorPane, causing the child to resize or reposition as the pane is resized. AnchorPane has no additional CSS properties beyond those inherited from Pane and Region.
