在未知高度div中垂直居中未知高度文本 [英] Center vertically a unknown height text in a unknown height div

问题描述

我知道这是一个常见的问题，我已经问过一个类似的问题。
但是我这次找不到解决方案。
我试图垂直居中的文本，可以有不同的高度在一个DIV，可以有不同的高度。
我只是想用CSS解决这个问题，而不用触摸HTML。

I know this is a common issue, and I've already asked a similar one. But I could not find the solution this time. I am trying to vertically center a text which can have different height in a DIV which can have different height. And I am trying to solve this only with CSS, without touching the HTML.

示例： http://jsfiddle.net/F8TtE/

 <div id="test">
    <div id="sumup">

        <h1 class="titre">Title</h1>
        <div id="date">hello guys</div>
    </div>
 </div>

我的目标是让文字沿垂直和水平方向集中在任何大小。

My goal is to have the text centered vertically and horizontally whatever its size.

推荐答案

这里是：

#test {
    text-align:center;
}
#test::before {
    content: '';
    display: inline-block;
    height: 100%;
    vertical-align: middle;
}
#sumup {
    display: inline-block;
    vertical-align: middle;
}

#test {
    height : 180px;
    text-align:center;
    background: yellow;
}

#sumup {
   	background-color: #123456;
}

#test:before {
    content: '';
    display: inline-block;
    height: 100%;
    vertical-align: middle;
  }
  #sumup {
    display: inline-block;
    vertical-align: middle;
  }

<div id="test">
		<div id="sumup">
			
			<h1 class="titre">Title</h1>
			<div id="date">hello guys</div>
		</div>
</div>

编辑：现在是2015年，感谢网络的变化。假设您不支持过时的浏览器，通常使用 Flex模型。

It's now 2015 and thankfully the web changes. Assuming you don't support obsolete browsers, it's usually simpler and cleaner to vertically center elements with the Flex model.

#test {
    display: flex;
    flex-direction: column;
    align-items: center;
    justify-content: center;
}

#test {
    height : 180px;
    background: yellow;
    display: flex;
    flex-direction: column;
    align-items: center;
    justify-content: center;
}

#sumup {
   	background-color: #123456;
}

<div id="test">
		<div id="sumup">
			<h1 class="titre">Title</h1>
			<div id="date">hello guys</div>
		</div>
</div>
