Examples

Both scrollbars

Use <ScrollArea.Corner> to prevent the scrollbars from intersecting.

Gradient scroll fade

Use the viewport overflow CSS variables to fade the scroll edges, which gradually increases in strength as the user scrolls away from the edges.

The CSS variables do not inherit by default to improve rendering performance in complex scroll areas with deep subtrees. To use them in child elements (or pseudo-elements on <ScrollArea.Viewport>), you must manually set each variable to inherit.

scroll-area.module.css

For SSR, a fallback can be used as part of the var() function to provide a default height.
