Question

我有一个3列布局，顶部有导航。 3列构造为带有容器的侧菜单，在该容器内是另一个侧面菜单，旁边有一个容器。

我试图让它成为所有div使用overflow-y: scroll在视口中滚动但是我目前的状态似乎被忽略而且整个页面都是滚动整体代替。

不确定我误解了什么。我用我当前的状态构建了一个Codepen。

这是你想要的效果吗？

我从height，outer-container和inner-side-menu

删除了inner-container媒体资源

＆＃13;

html body {
  height: 100vh;
  margin: 0;
}
#app {
  background: black;
}
.navigation {
  background: cyan;
  height: 60px;
}

.route-container {
  display: grid;
  grid-template-columns: 0.25fr 0.75fr;
  grid-template-rows: auto;
  grid-template-areas:
    "outer-side-menu outer-container";
  
  height: calc(100vh - 60px);
  background: magenta;
}
.outer-side-menu {
  background: orange;
  grid-area: outer-side-menu;
}
.outer-container {
  background: yellow;
  grid-area: outer-container;
  display: grid;
  grid-template-columns: 0.25fr 0.75fr;
  grid-template-rows: auto;
  grid-template-areas:
    "inner-side-menu inner-container";
    
  /* added */
  overflow: scroll;
  
  /* removed height: 100% */
}
.inner-side-menu {
  background: lime;
  grid-area: inner-side-menu;
  font-size: 144px;
    
  /* prevent horizontal scrolling */
  overflow-x: hidden;
}
.inner-container {
  background: red;
  grid-area: inner-container;
  font-size: 144px;
    
    
  /* prevent horizontal scrolling */
  overflow-x: hidden;

}

＆＃13;

<div id="app">
  <div class="navigation">Navigation</div>
  <div class="route-container">
    <div class="outer-side-menu">Side Menu</div>
    <div class="outer-container">
      <div class="inner-side-menu">Inner Side Menu Inner Side Menu Inner Side Menu</div>
      <div class="inner-container">Inner Container Inner Container Inner Container Inner Container</div>
    </div>
  </div>
</div>

您应该使用max-height:100%代替height:100%。尝试更改此内容。

.outer-side-menu {
  background: orange;
  grid-area: outer-side-menu;
  overflow-y: scroll;
  max-height: 100%;
}
.inner-side-menu {
    background: lime;
    grid-area: inner-side-menu;
    overflow-y: scroll;
    height: 100%;
    font-size: 144px;
}
.inner-container {
    background: red;
    grid-area: inner-container;
    overflow-y: scroll;
    height: 100%;
    font-size: 144px;
}
