具有固定的页眉，页脚和可滚动内容的自适应网格布局 [英] Responsive grid layout with fixed header, footer and scrollable content

问题描述

我正在尝试使用flexbox创建2列全高设计.当我将滚动添加到整个中间部分时，我会有一个奇怪的行为.如果父容器具有滚动条，则flex-grow/stretch似乎不会增长/拉伸其他项目.

I'm trying to create 2 column full height design by using flexbox. When I add scrolling to whole middle part then I have a strange behavior. It seems that flex-grow/stretch doesn't grow/stretch other items if parent container has a scrollbar.

这是我的小提琴.代码也如下所示:

Here is my fiddle. Code also given below:

html, body {
    height: 100%;    
}
#container {
    display: flex;
    flex-direction: column;
    height: 100%;
    
    width: 50%;
    background-color: red;
}

#container header {
    background-color: gray;
}
#container section {
    flex: 1 1 auto;
    overflow-y: auto;
    min-height: 0px;
}
#container footer {
    background-color: gray;
}
aside {
  width : 100px;
  background-color: blue;
}
article{
  width: 100%;
  display:flex;
  flex-direction: column;
}
article > div{
  flex: 1 1 auto;
}

#content {
  display:flex;   
}

<section id="container" >
<header id="header" >This is a header</header>
<section id="content">

      <br />

      With a lot of lines.
      <br />
      This is the content that
      <br />
      With a lot of lines.
      <br />
      <br />
      This is the content that
      <br />
      With a lot of lines.
      <br />
      <br />
      This is the content that
      <br />
      With a lot of lines.
      <br />
    </div>
    <footer id="footer" >This is a page footer</footer>      
  </article>
</section>
<footer id="footer" >This is a footer</footer>
</section>

基本上，我正在尝试介绍2种情况.如果我不需要滚动，则效果很好，但是一旦滚动，项目将无法正确拉伸:

Basically i'm trying to cover 2 scenarios. It works fine if i don't need to scroll but once i have a scroll the items doesn't stretch correctly:

推荐答案

要使此布局在最新的Firefox&截止到今天，Chorme(从2016年开始修改此答案)进行了以下更改:

To make this layout work in latest Firefox & Chorme as of today (revising this answer from 2016), I made the following changes:

1. 在body中添加了margin: 0，以允许container弯曲到视口高度.

1. Added margin: 0 to body to allow the container to flex to the viewport height.

将内容包裹在另一个section中的#content元素上，并将其设置为 column flexbox.

Wrap you the contents on #content element in another section and make it a column flexbox.

使内部section一个全高Flexbox并提供min-height: max-content和flex: 1.

Make the inner sectiona full-height flexbox and give min-height: max-content and flex: 1.

请参见下面的演示

html,
body {
  height: 100%;
  margin: 0; /* ADDED */
}

#container {
  display: flex;
  flex-direction: column;
  height: 100%;
  width: 50%;
  background-color: red;
}

#container header {
  background-color: gray;
}

#container > section { /* ADDED > selector */
  display: flex; /* ADDED */
  flex-direction: column; /* ADDED */
  flex: 1 1 auto;
  overflow-y: auto;
  min-height: 0px;
}

#container > section > section{ /* ADDED */
  display: flex;
  height: 100%;
  min-height: max-content; /* fixes chrome */
  flex: 1; /* fixes firefox */
}

#container footer {
  background-color: gray;
}

aside {
  width: 100px;
  background-color: blue;
  min-height: content;
}

article {
  width: 100%;
  display: flex;
  flex-direction: column;
}

article>div {
  flex: 1 1 auto;
}

上述解决方案充其量是 hacky ，它向我们展示了为什么弹性盒在2D布局中弱.答案是它不是专门为它设计的.但是 CSS Grids 是-看看一切都变得容易到位:

The above solution is hacky at best and shows us why a flexbox is weak in 2D layouts. The answer is it is just not designed for it. But CSS Grids are - see how easily everything falls into place:

1. 使#container为完整视口的 grid 元素.

使用grid-template-columns: 100px 1fr和 overflow 属性为 middle section一个 grid 容器提供一个 grid 容器，您差不多就完成了.

Make the middle section a grid container with grid-template-columns: 100px 1fr along with overflow property and you are almost done.

请参见下面的演示

body {
  margin: 0;
}

#container {
  display: grid;
  width: 50%;
  height: 100vh;
  background-color: red;
}

header, footer {
  background-color: gray;
}

#container section {
  display: grid;
  grid-template-columns: 100px 1fr;
  overflow-y: auto;
}

aside {
  background-color: blue;
}

article {
  display: flex;
  flex-direction: column;
}

article > div {
  flex: 1 1 auto;
}
