API reference

HoverCard

Extends the Base UI Preview Card Root — no modal prop; hover-open is built in. Not accessible to touch or screen-reader users by design — preview cards are a progressive enhancement over the underlying link, which remains fully operable on its own.

HoverCardTrigger

Renders a real link (<a>) and needs an href — preview cards exist to preview link destinations.
