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;

overscroll-behavior-inline: inherit;
overscroll-behavior-inline: initial;
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 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.
No scroll chaining occurs to neighbouring 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 comforably 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.


      <p><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.</p>
