Effect

Skeleton loading effects including pulse and shimmer animations. Use pulse for subtle breathing motion or shimmer for a scanning highlight that conveys active content loading.

Shape

Skeleton shape variants including default rectangle, pill, and round. Use pill for button or tag placeholders and round for avatar or icon placeholders to match the final content shape.

Slotted
