css - 如何在页面滚动之前滚动 div？

Question

我正在尝试复制这个网站的效果

当您滚动时，它先滚动右侧的 div，然后再滚动到最后的整个页面。怎么可能达到这种效果呢？是否可以纯粹使用 CSS 还是需要 JS？我一直在尝试使用溢出来复制它，但效果不一样。

你应该能够在 css postioning propertyfixed 的帮助下实现这一点。

#main {
  background-color: aqua;
}
#container {
  width: 40%;
  float: left;
  top: 20px;
  position: fixed;
}
#side-panel {
  float: right;
  width: 50%;
  background-color: white;
}
#footer {
  clear: both;
  background: green;
  width: 100%;
  position: relative;
  height: 100vh;
}

<div id="main">
  <div id="container">

    This is fixed

  </div>

  <div id="side-panel">

    Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has
    survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing
    software like Aldus PageMaker including versions of Lorem Ipsum. It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less
    normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem
    ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like). Contrary to popular belief, Lorem Ipsum is not simply random text.
    It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem
    Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written
    in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from a line in section 1.10.32. The standard chunk of Lorem Ipsum used since the 1500s
    is reproduced below for those interested. Sections 1.10.32 and 1.10.33 from "de Finibus Bonorum et Malorum" by Cicero are also reproduced in their exact original form, accompanied by English versions from the 1914 translation by H. Rackham. Lorem

  <div id="footer">
    This is footer
  </div>

</div>

在我的尝试中，我基本上使左侧面板固定，而右侧面板 float 到右侧。

但是我不确定这是否是最优雅的解决方案。
