The overscroll-behavior-inline CSS property sets the browser's behavior when the inline direction boundary of a scrolling area is reached.

See overscroll-behavior for a full explanation.


/* Keyword values */
overscroll-behavior-inline: auto; /* default */
overscroll-behavior-inline: contain;
overscroll-behavior-inline: none;

/* Global values */
overscroll-behavior-inline: inherit;
overscroll-behavior-inline: initial;
overscroll-behavior-inline: revert;
overscroll-behavior-inline: revert-layer;
overscroll-behavior-inline: unset;

The overscroll-behavior-inline 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 (e.g., "bounce" effects) is observed inside the element where this value is set. However, no scroll chaining occurs on neighboring scrolling areas; the underlying elements will not scroll. The contain value disables native browser navigation, including the vertical pull-to-refresh gesture and horizontal swipe navigation.


No scroll chaining occurs to neighboring scrolling areas, and default scroll overflow behavior is prevented.

Preventing inline overscrolling

In this demo 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 comfortably inside the viewport, but its content is given a large width so it will also scroll horizontally.

By default, when the inner box is scrolled and a scroll boundary is reached, the whole page will begin to scroll, which is probably not what we want. To avoid this happening in the inline direction, we've set overscroll-behavior-inline: contain on the inner box.


        <code>overscroll-behavior-inline</code> has been used to make it so that
        when the scroll boundaries of the yellow inner box are reached, the
        whole page does not begin to scroll.
