CSS图片垂直居中方法整理集合

一、基本方法：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<style type="text/css">
<!--
* {margin:0;padding:0}
div {
   width:500px;
   height:500px;
   border:1px solid #ccc;
   overflow:hidden;
   position:relative;
   display:table-cell;
   text-align:center;
   vertical-align:middle
   }
div p {
   position:static;
   +position:absolute;
   top:50%
   }
img {
   position:static;
   +position:relative;
   top:-50%;left:-50%;
   width:276px;
   height:110px
   }

-->
</style>

<div><p><img src="

二、标准浏览器下另类方法:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<style type="text/css">

</style>

三、标准浏览器严格型申明下：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<style type="text/css">
<!--
* {margin:0;padding:0}
div {
    width:500px;
    height:500px;
    line-height:500px;
    border:1px solid #ccc;
    overflow:hidden;
    position:relative;
    text-align:center;
    }
div p {
    position:static;
    +position:absolute;
    top:50%;
    vertical-align:middle
    }
img {
    position:static;
    +position:relative;
    top:-50%;left:-50%;
    width:276px;
    height:110px;
    vertical-align:middle
    }

-->
</style>

<div><p><img src="

四、利用字体大小的方法：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

五、最简单当然是背景图片的方法啦
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
