Question

我试图创造一个视差效果，我需要帮助。如何减慢页面上不同元素的滚动速度？我还应该补充一点，我已经下载了skrollr，但即使他们的教程也没有找到任何提及滚动速度的内容。

谢谢

没有直接影响网站滚动速度的方法。这是由浏览器和操作系统本身指导的。有一些方法可以通过设置内容滚动来伪造它，如jsfiddle所示。

如果你的目标是简单的paralaxx效果w3schools有一个great demo/tutorial。

我认为你所寻找的是像this这样的效果。你可以用CSS转换来做到这一点。

  .parallax {
    height: 500px; /* fallback for older browsers */
    height: 100vh;
    overflow-x: hidden;
    overflow-y: auto;
    -webkit-perspective: 300px;
    perspective: 300px;
  }

  .parallax__group {
    position: relative;
    height: 500px; /* fallback for older browsers */
    height: 100vh;
    -webkit-transform-style: preserve-3d;
    transform-style: preserve-3d;
  }

  .parallax__layer {
    position: absolute;
    top: 0;
    left: 0;
    right: 0;
    bottom: 0;
  }
  
  .parallax__group {
    -webkit-transition: -webkit-transform 0.5s;
    transition: transform 0.5s;
  }

  .parallax__layer--fore {
    -webkit-transform: translateZ(90px) scale(.7);
    transform: translateZ(90px) scale(.7);
    z-index: 1;
  }

  .parallax__layer--base {
    -webkit-transform: translateZ(0);
    transform: translateZ(0);
    z-index: 4;
  }

  .parallax__layer--back {
    -webkit-transform: translateZ(-300px) scale(2);
    transform: translateZ(-300px) scale(2);
    z-index: 3;
  }

  .parallax__layer--deep {
    -webkit-transform: translateZ(-600px) scale(3);
    transform: translateZ(-600px) scale(3);
    z-index: 2;
