/* sprite-loader-enable */
.flip_flops {
    width: 16px;
    height: 16px;
    background: url(./img/[email protected]);
}
.tram {
    width: 50px;
    height: 50px;
    background: url(./img/[email protected]);
}
.pie {
    width: 100px;
    height: 100px;
    background: url(./img/[email protected]);

2.Adapt Retina Screen

It's very easy to adapt Retina screen. You just need to use double size images and name them as [email protected]. sprite-loader will generate 1x images and media query automatically.

3.Disable Combination

sprite-loader will collect all the background and background-image attributes in css files to combine. Except for following circumstance:

1. Images that set the background-position and background-size.

   /* ignore images that set background-position */
   .bg1{background: url(1.png) no-repeat -10px -10px;}
   /* ignore images that set background-size的 */
   .bg2{background: url(2.png); background-size: 10px 10px;}
   

2. Image url that contain #spriteignore string.

   /* ignore all images that contain #spriteignore */
   .bg3{background: url(3.png#spriteignore);}
