HomeWeb Front-endHTML Tutorialdiv中的内容垂直居中的五种方法_html/css_WEB-ITnose

一、行高(line-height)法

如果要垂直居中的只有一行或几个文字,那它的制作最为简单,只要让文字的行高和容器的高度相同即可,比如:

p { height:30px; line-height:30px; width:100px; overflow:hidden; }

这段代码可以达到让文字在段落中垂直居中的效果。

二、内边距(padding)法

另一种方法和行高法很相似,它同样适合一行或几行文字垂直居中,原理就是利用padding将内容垂直居中,比如:

p { padding:20px 0; }

这段代码的效果和line-height法差不多。

三、模拟表格法

将容器设置为display:table,然后将子元素也就是要垂直居中显示的元素设置为display:table-cell,然后加上vertical-align:middle来实现。

html结构如下:

<div id="wrapper">    <div id="cell">        <p>测试垂直居中效果测试垂直居中效果</p>        <p>测试垂直居中效果测试垂直居中效果</p>    </div></div>

 

css代码:

#wrapper {display:table;width:300px;height:300px;background:#000;margin:0 auto;color:red;}#cell{display:table-cell; vertical-align:middle;}

 

实现如图所示:

遗憾的是IE7及以下不支持。

四、CSS3的transform来实现

css代码如下:

.center-vertical{  position: relative;  top:50%;  transform:translateY(-50%);}.center-horizontal{  position: relative;  left:50%;  transform:translateX(-50%); }

 

五:css3的box方法实现水平垂直居中

html代码:

<div class="center">  <div class="text">    <p>我是多行文字</p>    <p>我是多行文字</p>    <p>我是多行文字</p>  </div></div>

css代码:

.center {  width: 300px;  height: 200px;  padding: 10px;  border: 1px solid #ccc;  background:#000;  color:#fff;  margin: 20px auto;  display: -webkit-box;  -webkit-box-orient: horizontal;  -webkit-box-pack: center;  -webkit-box-align: center;    display: -moz-box;  -moz-box-orient: horizontal;  -moz-box-pack: center;  -moz-box-align: center;    display: -o-box;  -o-box-orient: horizontal;  -o-box-pack: center;  -o-box-align: center;    display: -ms-box;  -ms-box-orient: horizontal;  -ms-box-pack: center;  -ms-box-align: center;    display: box;  box-orient: horizontal;  box-pack: center;  box-align: center;}

 结果如图:
