CSS使图片变灰

雅安加油!

全局变灰:

html{
    -webkit-filter: grayscale(1);
            filter: progid:DXImageTransform.Microsoft.BasicImage(grayscale=1);
}

只对局部进行变灰:

(#id,.class,img,input......){
    -webkit-filter: grayscale(1);
            filter: progid:DXImageTransform.Microsoft.BasicImage(grayscale=1);
}
