四、扩展:在ie下模拟css3中的box-shadow阴影效果

方法一：可以使用IE的Shadow滤镜

• 基本语法：filter:progid:DXImageTransform.Microsoft.Shadow(color=’颜色值’, Direction=阴影角度（数值）,Strength=阴影半径（数值）);

• 注意：该滤镜必须配合background属性一起使用，否则该滤镜失效。

    .box-shadow{
        filter: progid:DXImageTransform.Microsoft.Shadow(color='#969696',Direction=135, Strength=5);/*for ie6,7,8*/
        background-color: #ccc;
        -moz-box-shadow:2px 2px 5px #969696;/*firefox*/
        -webkit-box-shadow:2px 2px 5px #969696;/*webkit*/
        box-shadow:2px 2px 5px #969696;/*opera或ie9*/
    }  

方法二：有些js和.htc的hack文件可以实现IE中的阴影效果。

ie-css3.htc是一个可以让IE浏览器支持部份CSS3属性的htc文件，不只是box-shadow，它还可以让你的IE浏览器支持圆角属性border-radius和文字阴影属性text-shadow。

它的使用方法是：下载它并放到你的服务器目录，在你的<head></head>里面写入下面的代码:

.div1 {
    -moz-box-shadow: 10px 10px 20px #000;
    -webkit-box-shadow: 10px 10px 20px #000;
    box-shadow: 10px 10px 20px #000;
    behavior: url(ie-css3.htc);
}

这个脚本的缺点是IE只支持一部分的box-shadow值。

需要注意：

• 当你使用了这个htc文件后，你的CSS里面，只要写有box-shadow, -moz-box-shadow或-webkit-box-shadow的任何一种，IE就会渲染。

• 当使用了这个htc文件后，你不能这样写box-shadow: 0 0 10px red; 而应该是box-shadow: 0px 0px 10px red; 否则IE中会失效。

• 不支持RGBA值中的alpha透明度。

• 不支持inset内阴影。

• 不支持阴影扩展。

• 阴影在IE中只会显示为黑色，不管你设置成其它什么颜色。

方法三：使用jQuery的插件jquery.boxshadow.js

使用方法很简单，将该文件和jquery版本库引入head标签，插入以下js效果代码：

<script type="text/javascript">
    $(document).ready(function(){
        if($.browser.msie) {
             $('.obj').boxShadow(-10,-10,5,"#0cc"); //obj元素使用了box-shadow
         }
    });
</script>  

注意：js中可以使用：obj.style.webkitBoxShadow=值（字符串）;obj.style.MozBoxShadow=值（字符串）;obj.style.boxShadow=值（字符串）;
