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;
}
