如何用CSS创建实心彩虹边框？

Question

如何使用CSS创建以下彩虹效果？

即顶部圆形边框,固体彩虹色停止(不插入HTML).

颜色是:#c4e17f. #f7fdca, #fad071, #f0766b, #db9dbe, #c49cdf, #6599e2, #61c2e4.

到目前为止我尝试了什么:

.container {
  background: #596678;
  width: 100%;
  height: 300px;
  display: flex;
  justify-content: center;
  align-items: center;
}

.top-round-rainbow {
  width: 50%;
  height: 50%;
  background: white;
  border-radius: 4px;
  
  background-image: repeating-linear-gradient(to right, #c4e17f 50px, #f7fdca 50px, #fad071 50px, #f0766b, #db9dbe, #c49cdf, #6599e2, #61c2e4);
}

<div class="container">
  <div class="top-round-rainbow">
  </div>
</div>

你不是那么遥远.只需要设置相同值的颜色停止,使它们作为纯色,背景大小只在顶部.

.container {
  background: #596678;
  width: 100%;
  height: 300px;
  display: flex;
  justify-content: center;
  align-items: center;
}

.top-round-rainbow {
  width: 400px;
  height: 50%;
  background: white;
  border-radius: 4px;
  
  background-image: repeating-linear-gradient(to right,
  #c4e17f 0px, #c4e17f 50px,
  #f7fdca 50px, #f7fdca 100px,
  #fad071 100px, #fad071 150px,
  #f0766b 150px, #f0766b 200px,
  #db9dbe 200px, #db9dbe 250px,
  #c49cdf 250px, #c49cdf 300px,
  #6599e2 300px, #6599e2 350px,
  #61c2e4 350px, #61c2e4 400px);
  background-size: 100% 10px;
  background-repeat:no-repeat;
}

<div class="container">
  <div class="top-round-rainbow">
  </div>
</div>
