Как можно сделать края у дива как на фото которое я прикрепил?

body,
header h1 {
  margin: 0;
  padding: 0;
}

/*height of wave = h = 50px*/
header {
  background: darkblue;

  width:  400px;
  height: 150px;
  color: #fff;
  padding: 8px;
  padding-bottom: 50px; /*h*/

position: relative;
  overflow: hidden;
}

header:before,
header:after {
  content: "";
  position: absolute;
  left: 0;
  right: 0;
  bottom: 25px; /*h/2*/
  height: 50px; /*h*/
  background: radial-gradient(closest-side, #fff, #fff 50%, transparent 50%);
  /*or farthest-side*/
  background-size: 50px 50px; /*h h*/
  background-position: 0 25px; /*0 h/2*/
  background-repeat: repeat-x;
}

header:after {
  background: radial-gradient(
    closest-side,
    transparent,
    transparent 50%,
    #fff 50%
  );
  /*or farthest-side*/
  background-size: 50px 50px; /*h h*/
  background-position: 25px -25px; /*h/2 -h/2*/
  background-repeat: repeat-x;
  bottom: -25px;
}

<header class="wave">
</header>
