profile-preview.tsx

item-details.tsx

PropTypeDefaultDescription
HoverCard propsReact.ComponentProps<typeof HoverCardPrimitive.Root>—All props from the Radix HoverCard Root primitive, forwarded to the shadcn HoverCard wrapper.
HoverCardTrigger propsReact.ComponentProps<typeof HoverCardPrimitive.Trigger>—All props from the Radix HoverCard Trigger primitive. The wrapper defaults asChild to true; className is also accepted and passed through.
HoverCardContent propsReact.ComponentProps<typeof HoverCardPrimitive.Content> & VariantProps<typeof hoverCardVariants>—All props from the Radix HoverCard Content primitive, plus the font variant. Content uses the retro font by default; font accepts "normal", "retro", or null. className is combined with the wrapper's relative positioning and variant classes.
Accessibility
- Use a focusable, semantically appropriate trigger, such as a link or button; the trigger defaults to asChild=true so it can compose with its child element.
- Keep hover-card content supplementary and do not make essential actions or information available only on hover.
- The two decorative frame overlays are marked aria-hidden="true" and do not add content to the accessibility tree.
- Radix primitive props are forwarded, allowing supported interaction and accessibility attributes to be supplied.
