Anchored content preview on hover or keyboard focus — Radix
|
|
HoverCard equivalent. Trigger is an <code><a></code>;
|
|
the floating panel reveals after <code>openDelay</code> (default
|
|
700ms) with a SafePolygon bridging trigger and content so the
|
|
pointer can travel without dismissing. Non-modal, no-op on touch
|
|
(navigates the link directly).

LinkPreview is decorative for assistive tech — the content
|
|
panel is sighted-user enhancement, not a primary information
|
|
channel. Screen readers should rely on the link's accessible
|
|
name (and surrounding context) to convey the destination. The
|
|
preview opens on keyboard focus too so sighted-keyboard users
|
|
get the affordance.
