Examples
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.

<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.
