不支持的css3属性缩写
项目中遇到一个奇怪的问题：那就是部分浏览器不支持CSS缩写的属性：
最常见的就是background属性
譬如background-size
另外说下opera内核的浏览器也是不支持：标注的为不支持
background:url(url) no-repeat center center scroll /50% 50% rgba(0,0,0,0);
IE6.7.8不支持的
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>让IE兼容background-size的方法</title>
<style>
.bgpic {
background-image: url('http://img0.bdstatic.com/img/image/6992fdda3cc7cd98d10273a6b34233fb80e7aec90cc.jpg');
background-size: cover;
filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(
src='http://img0.bdstatic.com/img/image/6992fdda3cc7cd98d10273a6b34233fb80e7aec90cc.jpg',
sizingMethod='scale');
}
</style>
</head>
<body>
<div class="bgpic" style="width:200px;height:100px;"></div>
