如何设置从中心位置到全直径的波纹效果动画

<div id="ripple-container"></div>

#ripple-container {
  width: 200px;
  height: 200px;
  background-color: #e0e0e0;
  position: relative;
  overflow: hidden;
}

var container = document.getElementById("ripple-container");

container.addEventListener("click", function(event) {
  // 获取点击位置相对于容器的坐标
  var x = event.clientX - container.offsetLeft;
  var y = event.clientY - container.offsetTop;

  // 创建波纹元素
  var ripple = document.createElement("span");
  ripple.className = "ripple";
  ripple.style.left = x + "px";
  ripple.style.top = y + "px";

  // 将波纹元素添加到容器中
  container.appendChild(ripple);

  // 动画结束后移除波纹元素
  setTimeout(function() {
    ripple.parentNode.removeChild(ripple);
  }, 1000);
});

.ripple {
  position: absolute;
  width: 0;
  height: 0;
  border-radius: 50%;
  background-color: rgba(0, 0, 0, 0.3);
  animation: ripple-effect 1s linear;
}

@keyframes ripple-effect {
  0% {
    transform: scale(0);
    opacity: 1;
  }
  100% {
    transform: scale(2);
    opacity: 0;
  }
}
