具有固定页眉、页脚和可滚动内容的响应式网格布局

Question

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，我有一个奇怪的行为。如果父容器有滚动条，似乎 flex-grow/stretch 不会增长/拉伸其他项目。

这是我的fiddle。代码如下：

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">
  <aside>
    test<br />
    test<br />
    test<br />
    test<br />
    test<br />

  <article id="article" >
    <div>

      <br />

      <br />
    </div>
    <footer id="footer" >This is a page footer</footer>      
  </article>
</section>
<footer id="footer" >This is a footer</footer>
</section>

基本上我试图涵盖 2 个场景。如果我不需要滚动，它可以正常工作，但是一旦我滚动，项目就不能正确拉伸：

Answer 1

为了使这种布局在今天最新的 Firefox 和 Chorme 中工作（从 2016 年修订这个答案），我进行了以下更改：

1. 将margin: 0 添加到body 以允许container 弯曲到视口高度。

2. 将#content 元素上的内容包装在另一个section 中，并使其成为列 flexbox。

3. 使内部的section成为一个全高的flexbox并给min-height: max-content和flex: 1。

请看下面的演示：

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;
}

  <header id="header">This is a header</header>

上面的解决方案充其量是 hacky，它向我们展示了为什么 flexbox 在 2D 布局中是 weak 的。答案是它不是为它设计的。但是CSS Grids 是 - 看看一切顺利到位：

1. 使#container成为一个完整的视口高grid元素。

2. 使 middle section 成为具有 grid-template-columns: 100px 1fr 和 overflow 属性的 grid 容器，您就差不多完成了。

请看下面的演示：

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;
}

  <header id="header">This is a header</header>
