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-start-end-shape of notch.

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: cyan;
  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-start-end-shape: notch;
}
