我需要帮助来制作这两个<div>'s (#side-nav and #content-wrapper) 独立滚动，

HTML:

<div id="wrapper">
    <div id="top-nav">
        Top nav
    </div>
    <div id="side-nav">
        <ul>
            <li>Thing</li>
            <li>Thing</li>
        </ul>
    </div>
    <div id="content-wrapper">
        <!-- Ton of conent here -->
    </div>
</div>

CSS:

#wrapper {
  width: 100%;
  background-color: #fff;
}

#top-nav {
  position: fixed;
  top: 0;
  height: 60px;
  width: 100%;
  background-color: green;
}

#side-nav {
  position: fixed;
  width: 250px;
  height:100vh;
  overflow-y: scroll;
  background-color: red;
}

#content-wrapper {
  margin: 60px 0 0 250px;
  padding: 0 30px;
  overflow-y: scroll;
  background-color: blue;
}

现在如果我滚动#side-nav到最后或顶部，#content-wrapper也会滚动。#side-nav即使没有那么多，也必须保持整页高度并固定<li>'s.

我很快就在这里制作了笔：

您需要设置内容包装器的高度，并设置左侧、右侧和顶部。

#side-nav {
  position: fixed;
  width: 250px;
  height:100vh;
  left: 0;
  right: 0;
  overflow-y: scroll;
  background-color: red;
  top: 60px;
}

#content-wrapper {
  margin: 60px 0 0 250px;
  padding: 0 30px;
  overflow-y: scroll;
  position: fixed;
  left: 0;
  top: 0;
  height:100vh;
  background-color: blue;
}
