以下是我用来实现上述布局的代码:
.header {
height: 50px;
}
.body {
position: absolute;
top: 50px;
right: 0;
bottom: 0;
left: 0;
display: flex;
}
.sidebar {
width: 140px;
}
.main {
flex: 1;
display: flex;
flex-direction: column;
}
.content {
flex: 1;
display: flex;
}
.column {
padding: 20px;
border-right: 1px solid #999;
}
<div class="header">Main header</div>
<div class="body">
<div class="sidebar">Sidebar</div>
<div class="main">
<div class="page-header">Page Header. Content columns are below.</div>
<div class="content">
<div class="column">Column 1</div>
<div class="column">Column 1</div>
<div class="column">Column 1</div>
</div>
</div>
</div>
我省略了用于样式化的代码。你可以在笔里看到所有这些。
上述方法是有效的，但是当内容区域的内容溢出时，会导致整个页面滚动。我只想让内容区域本身滚动，所以我在内容div中添加了overflow: auto。
现在的问题是，列本身并没有超出它们的父高度，所以边界也在那里被切断了。
这支笔显示了滚动问题。
如何将内容区域设置为独立滚动，同时仍然让其子区域超出内容框的高度?
工作位置:绝对;与flex一起:
使用Position: relative定位伸缩项。然后在它内部，添加另一个<div>元素:
position: absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;
这将元素扩展到其相对位置的父元素的边界，但不允许对其进行扩展。内部，溢出:自动;然后将按预期工作。
.all-0 {
top: 0;
bottom: 0;
left: 0;
right: 0;
}
p {
text-align: justify;
}
.bottom-0 {
bottom: 0;
}
.overflow-auto {
overflow: auto;
}

我遇到的一个问题是，要有一个滚动条，n元素需要指定高度(而不是%)。
诀窍是在每个列中嵌套另一组div，并将列父项的显示设置为flex-direction: column。
<style>
html, body {

padding: 0;
}

display: flex;
