将display: grid添加到父节点

下面的代码提供了设置滚动div的最小高度的能力，并通过使用flex使其具有其父div的100%高度。

CSS:

.main {
  display: flex;
  flex-direction: column;
}

.scroll {
  overflow: auto;
  flex: 1 0 50px;
}

HTML:

<div class="main">
  <div class="scroll">
    Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

注意:此答案适用于不支持Flexbox标准的旧浏览器。有关现代方法，请参见:https://stackoverflow.com/a/23300532/1155721

我建议你看看跨浏览器CSS的等高列，没有黑客。

基本上，以浏览器兼容的方式使用CSS来实现这一点并不简单(但是对于表来说很简单)，所以请找到一个适当的预打包解决方案。

同样，答案也取决于你想要100%的高度还是相同的高度。通常都是等高的。如果是100%高，答案就略有不同。

我可能有点晚了，但我找到了一个周围的工作，可能是一个hack。 首先给父层一个弯曲和100vh的高度

就像这样:

.parent {
   display: flex;
   justify-content: center;
   align-items: center;
   height: 100vh;/* Can be less depends on the container, basically this forces the element to expand */
}

对于父节点:

display: flex;

您应该添加一些前缀，例如http://css-tricks.com/using-flexbox/。

正如@Adam Garner所指出的，align-items:拉伸;不需要。它的用法也适用于父母，而不是孩子。如果你想定义儿童拉伸，你使用align-self。

.parent { 背景:红色; 填充:10 px; 显示:flex; ｝ .other-child { 宽度:100 px; 背景:黄色; 身高:150 px; 填充:.5rem; ｝ .child { 宽度:100 px; 背景:蓝色; ｝ < div class = "父" > < div class = "另一个孩子“> 仅用于拉伸父节点 < / div > < div class = "孩子" > < / div > < / div >

(在另一个回答中提到了Dmity的Less代码)我猜这是某种“伪代码”?

据我所知，尝试使用人造柱技术应该可以做到这一点。
