如何使div与父级相同的高度（显示为table-cell） [英] How to make div same height as parent (displayed as table-cell)

问题描述

我有一个容器div包含三个子div（内容不同） - 每个都和最高的一样高。我管理这个通过设置容器显示：table和子divs显示：table-cell等。

I got a container div containing three child divs (vary in content) - each as tall as the tallest one. I managed this by setting the container to display:table and the child divs to display:table-cell etc.

一切都很好，直到...

Everything worked just fine, until...

我在一个子div中插入了一个新的div，并尝试使它的高度为100％，所以它会伸展到与其父对象相同的高度，但是没有工作

I inserted a new div inside one of the child divs and tried to make it height:100% - so it would stretch to the same height as its parents, but that did not work.

    <div class="child">
        a<br />a<br />a
    </div>
    <div class="child">
        a<br />a<br />a<br />a<br />a<br />a<br />a
    </div>
    <div class="child">

CSS

.container {
    display: table;

.child {

    background-color: red;
    display: table-cell;
    vertical-align: top;
}
.content {
    height: 100%;
    background-color: blue;
}

推荐答案

子div到 display：inline-block;

.content {
    display: inline-block;
    height: 100%;
    width: 100%;
    background-color: blue;
}

.container {
  display: table;
}
.child {
  width: 30px;
  background-color: red;
  display: table-cell;
  vertical-align: top;
}
.content {
  display: inline-block;
  height: 100%;
  width: 100%;
  background-color: blue;
}

<div class="container">
  <div class="child">
    a
    <br />a
    <br />a
  </div>
  <div class="child">
    a
    <br />a
