# Scroll area

A React component in [Beamline](https://beamline.io/)'s [Layout](https://beamline.io/components/layout) category. Live demo: https://beamline.io/components/scroll-area

A native scroll region with thin overlay thumbs and edge fades that show only where more content waits; thumbs can be dragged or clicked.

## Use it for

- Scrolling regions inside panels: logs, lists, side panels, horizontal rows.

## Not for

- The page itself (let the browser scroll).

## Anatomy

- root
- viewport (native scroll)
- edge fades (mask)
- track
- thumb

## Variants

- **orientation**: vertical, horizontal, both
- **scrollbars**: auto, always

## States

- fits (no thumb, no fade)
- at top
- middle
- at end
- scrolling
- dragging thumb
- focus-visible (the look's focus ring on the root; the bar shows)

## Keyboard

- With a label the region is focusable: arrows, Page Up/Down, Home/End

## Motion

The bar arrives at once when scrolling, pointed at or focused and fades over --pui-duration-considered after hideDelay; edge fades switch with the scroll position (no animation). Focus is never animated.
