The overscroll-behavior property is used to set the behavior of the browser when the boundary of a scrolling area is reached. This property can be used to prevent unwanted scrolling in pages where there are multiple scroll areas. It is a shorthand for the overscroll-behavior-x and overscroll-behavior-y properties.
Syntax:
overscroll-behavior: auto | contain | none | initial | inherit
Property Values:
-
auto: It is used to set the scrolling behavior to default. The whole page along with the element 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</title><style>.container {display: flex;}.main-content {width: 200px;background-color: lightgreen;}.smaller-box {overscroll-behavior: auto;height: 100px;width: 125px;margin: 25px;overflow-y: scroll;}</style></head><body><h1style="color: green">GeeksforGeeks</h1><b>CSS | overscroll-behavior</b><p>overscroll-behavior: auto</p><divclass="container"><divclass="main-content">GeeksforGeeks is a computer scienceportal with a huge variety of wellwritten and explained computer scienceand programming articles, quizzes andinterview questions.

-
contain: It is used to set the scrolling behavior to default only on the element used. Scrolling the element further after it has reached the boundary will not scroll the elements behind it. No scroll-chaining would occur in the neighboring scrolling areas.
Example:
<!DOCTYPE html><html><head><title>CSS | overscroll-behavior</title><style>.container {display: flex;}.main-content {width: 200px;background-color: lightgreen;}.smaller-box {overscroll-behavior: contain;height: 100px;width: 125px;margin: 25px;overflow-y: scroll;}</style></head><body><h1style="color: green">GeeksforGeeks</h1><b>CSS | overscroll-behavior</b><p>overscroll-behavior: contain</p><divclass="container"><divclass="main-content">GeeksforGeeks is a computer scienceportal with a huge variety of wellwritten and explained computer scienceand programming articles, quizzes andinterview questions.

none: It is used to prevent scroll-chaining on all elements. The default scroll overflow behavior is also prevented.

<!DOCTYPE html><html><head><title>CSS | overscroll-behavior</title><style>.container {display: flex;}.main-content {width: 200px;background-color: lightgreen;}.smaller-box {overscroll-behavior: none;height: 100px;width: 125px;margin: 25px;overflow-y: scroll;}</style></head><body><h1style="color: green">GeeksforGeeks</h1><b>CSS | overscroll-behavior</b><p>overscroll-behavior: none</p><divclass="container"><divclass="main-content">GeeksforGeeks is a computer scienceportal with a huge variety of wellwritten and explained computer scienceand programming articles, quizzes andinterview questions.
