CSS | overscroll-behavior-y Property
The overscroll-behavior-y property is used to set the behavior of the browser when the vertical boundary of a scrolling area is reached. This can be used in websites where there are multiple scrolling areas and scrolling one area does not affect the page as a whole. This effect is known as scroll-chaining that can be enabled or disabled accordingly.
Syntax:
overscroll-behavior-y: auto | contain | none | initial | inherit
Property Values:
- auto: This is used to set the scrolling behavior to default on all the elements. The whole page will scroll even if the boundary of the element is reached. It is the default value.
Example:
<!DOCTYPE html>
<
html
>
<
head

<
title

CSS | overscroll-behavior-y
</

<

.container {

.smaller-box {
overscroll-behavior-y: auto;
height: 100px;
width: 125px;
margin: 25px;
