Specification

https://www.w3.org/TR/css-overscroll-1/#overscroll-behavior-properties

Summary

Shows elastic overscroll effects on non-root scroll containers. When a nested scrollable element reaches its scroll boundary, the overscroll affordance applies to that element instead of only the root scroller. This reduces the need for custom Javascript workarounds and can be controlled per element with overscroll-behavior.
