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 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.
HTML
<main> <div> <div> <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> </div> </div> </main>
CSS
main { height: 400px; width: 3000px; background-color: white; background-image: repeating-linear-gradient(to right, rgba(0,0,0,0) 0px, rgba(0,0,0,0) 19px, rgba(0,0,0,0.5) 20px); } main > div { height: 300px; width: 400px; overflow: auto; position: relative; top: 50px; left: 50px; overscroll-behavior-inline: contain; } div > div { height: 100%; width: 1500px; background-color: yellow; background-image: repeating-linear-gradient(to right, rgba(0,0,0,0) 0px, rgba(0,0,0,0) 19px, rgba(0,0,0,0.5) 20px); } p { padding: 10px; background-color: rgba(255,0,0,0.5); margin: 0; width: 360px; position: relative; top: 10px; left: 10px; }
