.customer-service {
  width: 100rpx;
  height: 100rpx;
  background-color: var(--themeColor);
  position: fixed;
  z-index: 10;
  bottom: 100rpx;
  right: 60rpx;
  border-radius: 50%;
  box-shadow: 0 0 20rpx rgba(189, 160, 102, 0.8);
}

.customer-service .btn {
  position: relative;
  z-index: 2;
  border-radius: 50%;
  width: 100%;
  height: 100%;
  opacity: 0;
}

.customer-service .pic {
  width: 100%;
  height: 100%;
  border-radius: 50%;
  position: absolute;
  top: 0;
  left: 0;
  bottom: 0;
  right: 0;
  margin: auto;
  z-index: 1;
}

.customer-service .line {
  width: 100%;
  height: 100%;
  border: 3px solid palevioletred;
  position: absolute;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
  margin: auto;
  border-radius: 50%;
  animation: emit 1s infinite;
}

@keyframes emit {
  0% {
  }
  100% {
    border-width: 1px;
    opacity: 0;
    transform: scale(1.5);
  }
}

animation: emit 1s infinite;//1s执行一次? 修改时间即可

动画效果放大1.5倍

@keyframes emit {
  0% {
  }
  100% {
    border-width: 1px;
    opacity: 0;
    transform: scale(1.5);
  }
}

Transform属性应用于元素的2D或3D转换。这个属性允许你将元素旋转，缩放，移动，倾斜等。
