HTML中的图片要足够多，撑出滚动条，JS中的滚轮事件才会触发。
CSS
1 * { 2 margin: 0; 3 padding: 0; 4 } 5 6 #main { 7 position: relative; 8 } 9 10 .box { 11 padding: 15px 0 0 15px; 12 float: left; 13 } 14 15 .picture { 16 padding: 10px; 17 border: 1px solid #aaa; 18 border-radius: 10px; 19 box-shadow: 0 0 1px #ccc, 0 0 2px #ccc; 20 } 21 22 img { 23 width: 150px; 24 height: auto; 25 }
img元素定宽之后，高度要设置为auto，否则在IE中有bug。

scroll事件需要添加到window上，如果添加到document上，IE8及之前版本没有效果。
动态添加的数据块有限，但是却能无限加载，原因未知。。。

与原生JS思路一样，只是写法不同，代码量少一半。。。
CSS3多栏布局

图片的排列顺序为从上到下，从左到右，与一般情况下的排列顺序不同。
IE10+支持这个属性。
