Values

auto

The default scroll overflow behavior occurs as normal.

contain

Default scroll overflow behavior (e.g., "bounce" effects) is observed inside the element where this value is set. However, no scroll chaining occurs on neighboring scrolling areas; the underlying elements will not scroll. The contain value disables native browser navigation, including the vertical pull-to-refresh gesture and horizontal swipe navigation.

none

No scroll chaining occurs to neighboring scrolling areas, and default scroll overflow behavior is prevented.
