CSS

We give the box some basic styles, which we've hidden for brevity. We also apply abox-shadow, aborder-radius of20px 40px / 60px 80px, and acorner-left-shape ofnotch 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;}
