html5鼠标爱心特效

HTML5鼠标爱心特效可以通过Javascript和CSS3实现。以下是一个简单的例子:

HTML代码:

<div class="container">
  <div class="heart"></div>
</div>

CSS代码:

.container {
  position: relative;
  width: 200px;
  height: 200px;
}

.heart {
  position: absolute;
  top: 50%;
  left: 50%;
  width: 20px;
  height: 20px;
  background-color: #f00;
  transform: translate(-50%, -50%) rotate(45deg);
  animation: heart 1s ease-out;
  animation-fill-mode: forwards;
  opacity: 0;
}

@keyframes heart {
  0% {
    transform: translate(-50%, -50%) rotate(45deg) scale(0);
    opacity: 0;
  }
  50% {
    transform: translate(-50%, -50%) rotate(45deg) scale(1.5);
    opacity: 1;
  }
  100% {
    transform: translate(-50%, -50%) rotate(45deg) scale(1);
    opacity: 0;
  }
}

Javascript代码:

document.addEventListener("mousemove", function(event) {
  var heart = document.querySelector(".heart");
  var container = document.querySelector(".container");
  var x = event.clientX - container.offsetLeft;
  var y = event.clientY - container.offsetTop;
  heart.style.left = x + "px";
  heart.style.top = y + "px";
});

当鼠标移动时，会在鼠标位置生成一个红色的爱心，并且会有一个动画效果。
