scss实现随机气泡大小，left百分比位置

@for $i from 1 through 7 {
  $size: random(40) + 30;
  $duration: random(8) + 4;
  $delay: random(3) + 1;
  $left: random(80) + 10%;

  .bubble:nth-child(#{$i}) {
    width: $size + px;
    height: $size + px;
    animation-duration: $duration + s;
    animation-delay: $delay + s;
    left: $left;
  }
}

气泡使用box-shadow: inset 0 0 8px #fff;

.bubble {
  position: absolute;
  border-radius: 50%;
  border: 2px solid #fff;
  box-shadow: inset 0 0 8px #fff;
  animation: flutter 10s infinite;
  opacity: 0;
}
