filter：<filter>+
适用于：所有元素
继承性：无
动画性：是
计算值：指定值
取值：
<filter>：要使用的滤镜效果。多个滤镜之间用空格隔开。
说明：
设置或检索对象所应用的滤镜效果。
最常用的滤镜效果是不透明效果，如果要实现50%的不透明度（其它高级浏览器的实现参阅opacity）：
示例代码：
div{filter:alpha(opacity=50);} /* for IE8 and earlier */ div{opacity:.5;} /* for IE9 and other browsers */以上2段代码的效果相同
对应的脚本特性为filter。
兼容性：
| Values | IE |
|---|---|
| Basic Support | 6.0-9.0 |
| 10.0-11.0 |
