# Hover card

A React component in [Beamline](https://beamline.io/)'s [Overlays](https://beamline.io/components/overlays) category. Live demo: https://beamline.io/components/hover-card

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.

- [Bottom sheet](https://beamline.io/components/bottom-sheet): A phone panel that rests at a peek and follows the finger to full height; a flick down closes it, and the handle works from the keyboard.
