}

body {
  display: flex;
  justify-content: center;
  align-items: center;
}

.box {
  width: 300px;
  height: 300px;
  border-radius: 5px;
  box-shadow: 0 2px 30px rgba(black, .2);
  background: lighten(#f0f4c3, 10%);
  position: relative;
  overflow: hidden;
  transform: translate3d(0, 0, 0);
}

.wave {

  margin-left: -250px;
  margin-top: -250px;

  animation: drift 3000ms infinite linear;
}

.wave.-three {

}

.wave.-two {
