# Showcase

The flagship XWUISpinner demo. It covers the small/medium/large sizes, the primary/secondary/white colors, a blurred blocking overlay over real content, programmatic `show()`/`hide()` control, and a real-world button-loading pattern that swaps a Save button's label for a small spinner.

Every spinner mounts into its own child div (or button) because an XWUI component clears its container on construct.
