这个动画中的圆圈是如何扭曲的？

Question

使用此代码点反弹，但我不知道如何进行转换以改变点的形状。

我在 https://lottiefiles.com/87015-loading 找到了这个设计，但我无法提取 CSS。它给了我 json 但我需要 CSS.

这是动画：

.dot-typing {
  position: relative;
  left: -9999px;
  width: 10px;
  height: 10px;
  border-radius: 5px;
  background-color: #9880ff;
  color: #9880ff;
  box-shadow: 9984px 0 0 0 #9880ff, 9999px 0 0 0 #9880ff, 10014px 0 0 0 #9880ff;
  animation: dotTyping 1s infinite linear;
}

@keyframes dotTyping {
  0% {
    box-shadow: 9984px 0 0 0 #9880ff, 9999px 0 0 0 #9880ff, 10014px 0 0 0 #9880ff;
  }
  16.667% {
    box-shadow: 9984px -10px 0 0 #9880ff, 9999px 0 0 0 #9880ff, 10014px 0 0 0 #9880ff;
  }
  33.333% {
    box-shadow: 9984px 0 0 0 #9880ff, 9999px 0 0 0 #9880ff, 10014px 0 0 0 #9880ff;
  }
  50% {
    box-shadow: 9984px 0 0 0 #9880ff, 9999px -10px 0 0 #9880ff, 10014px 0 0 0 #9880ff;
  }
  66.667% {
    box-shadow: 9984px 0 0 0 #9880ff, 9999px 0 0 0 #9880ff, 10014px 0 0 0 #9880ff;
  }
  83.333% {
    box-shadow: 9984px 0 0 0 #9880ff, 9999px 0 0 0 #9880ff, 10014px -10px 0 0 #9880ff;
  }
  100% {
    box-shadow: 9984px 0 0 0 #9880ff, 9999px 0 0 0 #9880ff, 10014px 0 0 0 #9880ff;
  }
}

  transform: translateY(-1px) /* just to hide a distubing line that show up on animation */
  
}

你可以尝试把玩它以获得你想要的。
