API reference

PropTypeDefaultDescription
childrenReact.ReactNode—Required card content rendered inside the spotlight container.
radiusnumber350Radius in pixels of the cursor-following radial spotlight mask.
colorstring"#262626"CSS color used for the spotlight layer revealed around the pointer.
classNamestring—Optional classes merged with the component's default container classes using `cn`.
...propsReact.HTMLAttributes<HTMLDivElement>—All other standard React HTML attributes for a div, including `id`, `style`, `aria-*`, `data-*`, and event handlers. These are spread onto the outer container.

Accessibility

  • The component renders a plain div and does not provide an inherent semantic role, keyboard interaction, or focus behavior.
  • Use semantic headings, text, links, and buttons inside the card so its content remains accessible to assistive technology.
  • The canvas reveal layer is decorative and has pointer events disabled; do not rely on the visual effect to communicate essential information.
  • Ensure text and interactive controls maintain sufficient contrast against the dark background.
  • If the entire card is intended to be interactive, place a semantic link or button inside it rather than assigning an interactive role to the div without implementing keyboard behavior.
