Limited availability

The corner-left-shape CSS property specifies the shape of both the corners on a box’s left-hand edge, within their border-radius area.

For a full description of corner shape behavior and multiple examples, see the corner-shape shorthand property page.

Constituent properties

The corner-left-shape property is a shorthand for the following physical properties:

Syntax

/* Single keyword value set for both corners */
corner-left-shape: round;
corner-left-shape: bevel;

/* Single superellipse() value set for both corners */
corner-left-shape: superellipse(1.2);
corner-left-shape: superellipse(-2.5);

/* Top corner, bottom corner */
corner-left-shape: round bevel;
corner-left-shape: bevel superellipse(1.2);

/* Global values */
corner-left-shape: inherit;
corner-left-shape: initial;
corner-left-shape: revert;
corner-left-shape: revert-layer;
corner-left-shape: unset;

Values

The corner-left-shape property is specified using one or two <corner-shape-value> values:

  • If one value is used, it specifies the shape of both left-hand corners.
  • If two values are used, the first one specifies the shape of the top-left corner, and the second one specifies the shape of the bottom-left corner.

CSS

We give the box some basic styles, which we’ve hidden for brevity. We also apply a box-shadow, a border-radius of 20px 40px / 60px 80px, and a corner-left-shape of notch bevel.

body {
  font-family: "Helvetica", "Arial", sans-serif;
  width: 240px;
  margin: 20px auto;
}

div {
  width: 100%;
  height: 180px;
  display: flex;
  justify-content: center;
  align-items: center;
  background-color: green;
  background-image: linear-gradient(
    to bottom,
    rgb(255 255 255 / 0),
    rgb(255 255 255 / 0.5)
  );
}

div {
  box-shadow: 1px 1px 3px gray;
  border-radius: 20px 40px / 60px 80px;
  corner-left-shape: notch bevel;
}
