.sub {
    float: left;
    width: 200px;
    height: 300px;
    margin-left: -100%;//这个地方要注意了margin-left设置为负值得话，位置往左移动，当移出这一行时，就会跑到上一行去，然后继续往左移动，如果margin-left设置为正值的话，位置就会往右移动，并且会一直往右动，并不会跳到下一行去。
    background-color: rgba(0, 255, 0, .5);
}
.extra {
    float: left;
    width: 180px;
    height: 300px;
