我页面周围的边框正在阻止元素悬停工作[重复]

Question

我的网页周围有一个边框，可以防止将鼠标悬停在元素上。 在下面的示例中，绿色框在悬停时进行缩放，但不会。

如果我在body::before 标签中添加一个否定的z-index，它就可以工作。但是当页面滚动时，所有文本都会超出边框。

我需要边框始终位于顶部，并且悬停仍然有效。

.zoom {
  padding: 50px;
  background-color: green;
  transition: transform .2s;
  width: 50px;
  height: 50px;
  margin: 0 auto;
}

.zoom:hover {
  -ms-transform: scale(1.5);
  /* IE 9 */
  -webkit-transform: scale(1.5);
  /* Safari 3-8 */
  transform: scale(1.5);
}

.lorem {
  width: 300px;
  margin: auto;
}

body::before {
  content: '';
  position: fixed;
  top: 0px;
  left: 0px;
  right: 0px;
  bottom: 0px;
  border: 15px solid #30582b;
  padding: 0px;
}

<div class="zoom"></div>
<div class="lorem">

在边框的伪元素上设置pointer-events: none：

.zoom {
  padding: 50px;
  background-color: green;
  transition: transform .2s;
  width: 50px;
  height: 50px;
  margin: 0 auto;
}

.zoom:hover {
  -ms-transform: scale(1.5);
  /* IE 9 */
  -webkit-transform: scale(1.5);
  /* Safari 3-8 */
  transform: scale(1.5);
}

.lorem {
  width: 300px;
  margin: auto;
}

body::before {
  content: '';
  position: fixed;
  top: 0px;
  left: 0px;
  right: 0px;
  bottom: 0px;
  border: 15px solid #30582b;
  padding: 0px;
  pointer-events: none;
}

<div class="zoom"></div>
<div class="lorem">
