css 画一个圆角渐变色边框

效果如图：

.border-box {
  width: 150px;
  height: 300px;
  box-shadow: 0px 2px 14px 0px rgba(0, 0, 0, 0.04);
  border: 2px solid transparent;
  border-radius: 20px;
  background-clip: padding-box, border-box;
  background-origin: padding-box, border-box;
  background-image: linear-gradient(to right, #fff, #fff),
    linear-gradient(
      180deg,
      rgba(255, 82, 119, 1) 0%,
      rgba(167, 117, 255, 1) 100%
    );
}
