需要注意的是，只能是background属性中的背景图片和颜色混合，而且只能在一个background属性中。

CSS3 backgrounds多背景IE9+浏览器就开始支持了。因此，你想混合多图，就是要逗号，一个一个写在background属性中就可以了，例如本Demo的两个妹子：

.box {
    background: url(mm1.jpg) no-repeat center, url(mm2.jpg) no-repeat center; 
}

 

 

 

 

 

 

.warp-bj{
    background-image: url(../images/bj.jpg),
                      url(../images/hy01.png);
    background-repeat: no-repeat;
    width: 720px;
    height: 1280px;
    -webkit-background-blend-mode: screen;
    -webkit-animation:bjAnimation 7500ms linear 500ms infinite alternate;
    background-blend-mode: screen;
    animation:bjAnimation 7500ms linear 500ms infinite alternate;
}
