html - 固定位置透视

Question

这是我的 JS FIDDLE 。

我想要我的 div id="text"固定。但它不适用于我的代码...问题是我需要将所有内容保留在我的 div id="wrapper" 中.我能怎么做？如果您有其他解决方案可以对我的图像产生视差效果(仅使用 css)，请告诉我。

body {
  overflow-x: hidden;
  margin:0;
}

#text {
  font-size: 70px;
  height: 100%;
  width: 100%;
  position: fixed;
}
#intro {
  font-size: 30px;
  width: 100%;
  border:3px solid yellow;
  position: absolute;
}

#wrapper {

  transform-style: preserve-3d;
  height: 100%;
  perspective: 1px;
  overflow-x: hidden;
  border:3px solid cyan;
  position: fixed;
  top: 0;
  left: 0;
  width: 100%;

}

#wrapper section {

    position: relative;
    height: 200px;
    width: 300px;
    background:pink;
    box-sizing: border-box;
    border:3px solid red;
    transform-style: inherit;
    overflow: hidden; 
    margin: 100px;

  }

#wrapper section .back {
      width: 300px;

      border:3px solid green;
      transition: transform 1s ease-out;
      height:200px;
      background-position: center center;
      transform: translateZ(-0.6px) scale(1.5); }

.back {
    background-image: url(http://wallpaper-gallery.net/images/background-image/background-image-18.jpg); }





#wrapper section .back:hover {

  opacity: 0.5;
  transform:translateZ(-0.4px) scale(2.6); }

这里是:

body {
  overflow-x: hidden;
/*    position:static;*/
    margin:0;

}

#text {
  font-size: 70px;
  height: 100%;
  width: 100%;
  position: fixed;
  pointer-events: none;
}
#intro {
  font-size: 30px;
  width: 100%;
  border:3px solid yellow;
  position: absolute;
}

#wrapper {

  transform-style: preserve-3d;
  height: 100%;
  perspective: 1px;
  overflow-x: hidden;
  border:3px solid cyan;
  position: fixed;
  top: 0;
  left: 0;
  width: 100%;

}

#wrapper section {

    position: relative;
    height: 200px;
    width: 300px;
    background:pink;
    box-sizing: border-box;
    border:3px solid red;
    transform-style: inherit;
    overflow: hidden; 
    margin: 100px;

  }

#wrapper section .back {
      width: 300px;

      border:3px solid green;
      transition: transform 1s ease-out;
      height:200px;
      background-position: center center;
      transform: translateZ(-0.6px) scale(1.5); }

.back {
    background-image: url("http://wallpaper-gallery.net/images/background-image/background-image-18.jpg"); }





#wrapper section .back:hover {

  opacity: 0.5;
  transform:translateZ(-0.4px) scale(2.6); }

<div id="wrapper">
  <div id="intro">

您需要将 real fixed 元素放在 DOM 的最后(作为 #wrapper 的兄弟)并给它 pointer -events:none 所以它允许 pointer-events(包括 scroll)传递给另一个 fixed 定位元素(#wrapper，它包含其余内容)需要滚动才能使视差效果发生。
