从上述的效果图可以看出，此页面的布局比较简单，采用常规的布局就可以实现

CSS / JavaScript 知识点

• backdrop-filter 属性回顾
• mousemove 事件

实现页面布局

<section>
  <h2>Frosted Glass</h2>
  <div class="glass"></div>
</section>

section {
  position: relative;
  display: flex;
  justify-content: center;
  align-items: center;
  min-height: 100vh;
  background: url(./bg.jpg) center;
  background-attachment: fixed;
  background-size: cover;
  overflow: hidden;
}

section h2 {
  font-size: 5em;
  color: #fff;
  pointer-events: none;
  text-shadow: 0 10px 20px rgba(0, 0, 0, 0.5);
}

section .glass {
  position: absolute;
  pointer-events: none;
  transform: translate(-50%, -50%);
  width: 300px;
  height: 200px;
  box-shadow: 0 25px 50px rgba(0, 0, 0, 0.2);
  background: transparent;
  backdrop-filter: blur(10px);
  transition: 0.5s;
}

实现毛玻璃跟随鼠标移动

毛玻璃跟随鼠标移动，我们可以使用mousemove事件来完成功能实现。

document.addEventListener("mousemove", (e) => {
  const glass = document.querySelector(".glass");
  glass.style.left = e.offsetX + "px";
  glass.style.top = e.offsetY + "px";
});
