CSS overflow-y Property

The overflow-y property specifies whether the content should be hidden, visible or scrolls vertically when the content overflows the element’s top and bottom edges. This property is one of the CSS3 properties.

The overflow-y property has four main values: visible, hidden, auto and scroll.

If the value of overflow-y is set to visible, the value of overflow-x, by default, will be set to visible. If the value of overflow-y is set to scroll, auto, or hidden, the value of overflow-x will be set to auto.
Initial Value visible
Applies to Block-containers, flex containers and grid containers.
Inherited No.
Animatable No.
Version CSS3

The overflow-x property can be used to define clipping the right and left sides.
