CSS

We give the box some basic styles, which we've hidden for brevity. We also apply a box-shadow, a border-radius of 25% 100px, and a corner-top-left-shape of scoop.

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: orange;
  background-image: linear-gradient(
    to bottom,
    rgb(255 255 255 / 0),
    rgb(255 255 255 / 0.5)
  );
}

css

  box-shadow: 1px 1px 3px gray;
