The overscroll-behavior-y property is specified as a keyword chosen from the list of values below.


The default scroll overflow behavior occurs as normal.
Default scroll overflow behavior is observed inside the element this value is set on (e.g. "bounce" effects or refreshes), but no scroll chaining occurs to neighbouring scrolling areas, e.g. underlying elements will not scroll.
No scroll chaining occurs to neighbouring scrolling areas, and default scroll overflow behavior is prevented.
