CSS implements div shadow effect with good compatibility

The shadow effect certainly looks cool. Firefox and Safari/Chrome support the box-shadow attribute through private properties. Box-shadow can achieve the shadow effect. However, IE does not support the box-shadow attribute, but the shadow effect can be achieved through the shadow filter.

css"><style type="text/css">
div {
    width:500px; height:500px; margin:0px; background:#FFFFFF;
/*
第一个参数是x轴阴影段长度
第二个参数是y轴阴影段长度
第三个参数是往四周阴影段长度
第四个参数是阴影段颜色
*/
    box-shadow:0px 0px 10px #CCCCCC;
    -moz-box-shadow:0px 0px 10px #CCCCCC;
    -webkit-box-shadow:0px 0px 10px #CCCCCC;
/*direction 阴影角度 0°为从下往上 顺时针方向 strength 阴影段长度*/
    -ms-filter:"progid:DXImageTransform.Microsoft.Shadow(color=#E9E9E9, direction=0, strength=6)\
                progid:DXImageTransform.Microsoft.Shadow(color=#E9E9E9, direction=90, strength=6)\
                progid:DXImageTransform.Microsoft.Shadow(color=#E9E9E9, direction=180, strength=6)\
                progid:DXImageTransform.Microsoft.Shadow(color=#E9E9E9, direction=270, strength=6)";
    *filter:progid:DXImageTransform.Microsoft.Shadow(color=#E9E9E9, direction=0, strength=6)
            progid:DXImageTransform.Microsoft.Shadow(color=#E9E9E9, direction=90, strength=6)
            progid:DXImageTransform.Microsoft.Shadow(color=#E9E9E9, direction=180, strength=6)
            progid:DXImageTransform.Microsoft.Shadow(color=#E9E9E9, direction=270, strength=6);
}
