Overflow-x:hidden也隐藏了垂直内容

Question

我有一个400px宽的DIV,它包含两个并排的DIV,每个DIV的宽度为400px,高度为600px.两个DIV的宽度是固定的,但高度可以变化.我想隐藏第二个DIV并完全显示第一个DIV,而DIV内部没有滚动.

我想,我的解决方案是隐藏溢出-x.这似乎也隐藏了y溢出.

这是我的代码:

#schools-sub-nav {
}
#schools-container {
  width: 400px; /* Set the width of the visible portion of content here */
  background-color: fuchsia;
  position: relative;
  overflow-x: hidden;
}
#schools-list {
  width: 400px; /* Set the width of the visible portion of content here */
  height: 600px; /* Delete the height, let the content define the height */
  background-color: purple;
  position: absolute;
  top: 0;
  left: 0;
}
#boards-list {
  width: 400px; /* Set the width of the visible portion of content here */
  height: 600px; /* Delete the height, let the content define the height */
  background-color: green;
  position: absolute;
  top: 0;
  left: 400px;
}

<div id="schools-sub-nav"> <a href="#schools-list">Schools List</a> // <a href="#boards-list">Boards List</a> </div>
<div id="schools-container">
    <div id="schools-list"> One </div>
    <div id="boards-list"> Two </div>
</div>

我希望#schools-list是可见的,但由于某种原因overflow-x: hidden在#schools-container隐藏它.

您使两个 div（具有绝对位置）的方式使溢出规则无效！

你需要改变位置类型（正常/非绝对），我建议使用浮动，最后，你想要应用溢出的容器div，需要有一种方法来适应它，比如在末尾放置一个div clear: both（在使用浮动的情况下）。

编辑：我刚刚尝试过，您可以按照上面的建议隐藏第二个 div，并在内部添加另一个宽度非常大的周围 div，并将主容器 div更改overflow-x为。overflow

像这样：

<div id="schools-container">
  <div id="schools-container-inside">
     <div id="schools-list"> One </div>
     <div id="boards-list"> Two </div>
  </div>
</div>

然后是CSS（我注释了原来未使用的CSS并在最后添加了新的div类）：

#schools-container {
    width: 400px; /* Set the width of the visible portion of content here */
    background-color: fuchsia;
    position: relative;
    /*overflow-x: hidden;*/
    overflow: hidden;
}
#schools-list {
    width: 400px; /* Set the width of the visible portion of content here */
    height: 600px; /* Delete the height, let the content define the height */
    background-color: purple;
    /*
    position: absolute;
    top: 0;
    left: 0;
    */
    float: left;
}
#boards-list {
    width: 400px; /* Set the width of the visible portion of content here */
    height: 600px; /* Delete the height, let the content define the height */
    background-color: green;
    /*
    position: absolute;
    top: 0;
    left: 400px;
    */
    float: left;
}
#schools-container-inside {
    width: 10000px;
    overflow: hidden;
}
