Hover card
A React component in Beamline's Overlays category.
A preview of a person, link or record on hover or keyboard focus, without leaving the page; HoverCardProfile is the standard person preview.
Use it for
- Previewing a mentioned person, a linked document or a record id.
Not for
- Essential information or actions (put them on the page).
- Touch-first screens: they never see it.
Anatomy
- trigger (a link or button)
- surface
- HoverCardProfile: avatar, name, role, about, facts
Variants
- side: top, right, bottom, left
- align: start, center, end
States
- closed
- opening (400 ms)
- open
- closing (200 ms grace)
Keyboard
- Focus on the trigger opens it
- Escape closes it
Motion
Grows from the trigger over --pui-motion-in. Opens out of its trigger (_shared/overlay.module.css, source morph): the layer starts as the trigger's own box, offset onto it, and grows; the side next to the trigger is there at once so the nearest rows read within the ruled 90 ms, the far side settles by ~200 ms, content fades in over 90 ms; it closes back into the trigger in 180 ms. Until it has grown the press that opened it cannot land on a row. Reduced motion: it appears.

- Tooltip: Short supporting text for a control: opens after a moment on hover and at once on keyboard focus; inside a toolbar group the next one opens instantly.
