API reference

PropTypeDefaultDescription
itemsCard[]—Required array of cards to render. Each card has an id: number, name: string, designation: string, and content: React.ReactNode.
offsetnumber | undefined—Optional vertical offset between stacked cards. The source uses 10 when this value is falsy.
scaleFactornumber | undefined—Optional scale reduction applied per card depth. The source uses 0.06 when this value is falsy.

Accessibility

  • The component renders cards as non-semantic div elements and does not provide built-in headings, landmarks, or interactive controls.
  • All cards remain in the DOM while the stack changes visually; ensure the card content is understandable in source order and does not rely only on visual layering.
  • The component has no built-in pause, stop, or manual navigation control despite changing every five seconds; provide an alternative or avoid placing essential time-sensitive information only in this animation.
  • Use meaningful text in name, designation, and content, and preserve sufficient contrast when customizing the content or surrounding styles.
  • If card content includes interactive elements, verify keyboard order and focus visibility because the visual stacking does not change DOM order. The source does not set aria-hidden on cards behind the top card.
