Syntax

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

Values

auto
The default scroll overflow behavior occurs as normal.
contain
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.
none
No scroll chaining occurs to neighbouring scrolling areas, and default scroll overflow behavior is prevented.

Formal syntax

contain | none | auto

Examples

In our simple overscroll-behavior-x example (see source code also), we have two block-level boxes, one inside the other. The outer box has a large width set on it so the page will scroll horizontally. The inner box has a small width (and height) set on it so it sits comforably inside the viewport, but its content is given a large width so it will scroll horizontally.

By default, when the inner box is scolled and a scroll boundary is reached, the whole page will begin to scroll, which is probably not what we want. To avoid this, you can set overscroll-behavior-x: contain on the inner box:

main > div {
  height: 300px;
  width: 500px;
  overflow: auto;
  position: relative;
  top: 100px;
  left: 100px;
  overscroll-behavior-x: contain;
}
