如何在布局中制造波纹

<button class="ripple-button">Click me</button>

.ripple-button {
  position: relative;
  width: 200px;
  height: 50px;
  background-color: #007bff;
  color: #fff;
  border: none;
  outline: none;
  cursor: pointer;
}

.ripple-button::before {
  content: "";
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  background-color: rgba(255, 255, 255, 0.4);
  border-radius: 50%;
  opacity: 0;
  transform: scale(0);
  pointer-events: none;
  transition: transform 0.3s ease-out, opacity 0.3s ease-out;
}

.ripple-button:hover::before {
  opacity: 1;
  transform: scale(1);
}

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