图片大小 128 * 128

transition 定义过度效果，
1、可同时设置几个css样式，
2、可定义transform（2d 3d 转换）的过度效果
transition: width 2s, height 2s, transform 2s;

-moz-transition: width 2s, height 2s, -moz-transform 2s;

-webkit-transition: width 2s, height 2s, -webkit-transform 2s;

-o-transition: width 2s, height 2s,-o-transform 2s;
