如何让CSS中的高度响应？

Question

我有一个像这样的html

<div class="container">
   <div class="content-1"></div>
   <div class="content-2"></div>
</div>

我希望它的工作原理是，如果content-1的高度为480px，则content-2将跟随content-1的高度。我的宽度还不错，但我的身高跟不上。

如何在css中做到这一点？

我的css代码是

.container{
 clear: both;
}
.content-1{
 width:66.66%;
 position: static;
 background-image: url("../images/path1");
 background-repeat: no-repeat;
 background-size: cover;
}

.content-2{
 width:33.33%;
 position: static;
 background-image: url("../images/path2");
 background-repeat: no-repeat;
 background-size: cover;
}

.flex-container {
  padding: 0;
  margin: 0;
  list-style: none;
  
  display: -webkit-box;
  display: -moz-box;
  display: -ms-flexbox;
  display: -webkit-flex;
  display: flex;
  
  -webkit-flex-flow: row wrap;
  justify-content: space-around;
}

.flex-item {
  background: tomato;
  padding: 5px;
  width: 200px;
 
  margin-top: 10px;
 
  color: white;
  font-weight: bold;
  font-size: 3em;
  text-align: center;
 word-break: break-all;
}

<div class="container flex-container">
   <div class="content-1 flex-item">orem 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</div>
   <div class="content-2 flex-item">1</div>
</div>

Answer 2

你能试试这段代码吗：

.container {
    display: table;
}
.content-1, .content-2 {
    display: table-cell;
}

Answer 3

在这种情况下，您可以使用CSS3 Flexbox。container类将具有display:flex，并且所有的子类都将设置为相同的高度。

​

.container {
  display:flex; 
 
}

.content-1 {
  border:1px solid #000000;
  width:50%;
   height:480px;
  }

.content-2 {
  border:1px solid #ff0000;
  width:50%;
  }

<div class="container">
   <div class="content-1">Content 1</div>
   <div class="content-2">Content 2</div>
</div>
