Basic corner-end-start-shape usage

HTML

The markup for this example contains a single <div> element.

<div></div>

CSS

We give the box some basic styles, which we've hidden for brevity. We also apply a box-shadow, a border-radius of 60px / 20%, and a corner-end-start-shape of bevel.

div {
  box-shadow: 1px 1px 3px gray;
  border-radius: 60px / 20%;
  corner-end-start-shape: bevel;
}
