corner-left-shape

Constituent properties

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

• corner-top-left-shape
• corner-bottom-left-shape

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.

Formal definition

Formal syntax

corner-left-shape = 
  <'corner-top-left-shape'>{1,2}  

<corner-top-left-shape> = 
  <corner-shape-value>  

<corner-shape-value> = 
  round             |
  scoop             |
  bevel             |
  notch             |
  square            |
  squircle          |
  <superellipse()>  

<superellipse()> = 
  superellipse( <number [-∞,∞]>  |
  infinity                       |
  -infinity )

Basic corner-left-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 20px 40px / 60px 80px, and a corner-left-shape of notch bevel.

body {
  font-family: Arial, Helvetica, 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;
}
