css3,环绕圆环 loading,小组件

一个loading的小组件, 给其他模块调用。先上图

type:cat

type:ball

第一幅loading，老鼠是一个圆形的背景图片，已经转成base64。 小猫也是图片 也已经转成base64.

老鼠的父div，一直在rotate。

小猫的眼珠，是不动的。动的是 小猫的眼球div，眼球div一直在rotate，眼珠是绝对定位在眼球的底部，这样眼球转起来的时候，给人的感觉就是眼珠再转。

第二幅loading的小球也是上面这个原理。

文字的动画，是用宽度，和透明度的变化来实现的。

源代码 css 代码是用less 编写的。并且这个type，涉及到模块化的一点东西。所以下面就贴出，2个loading的 dom和css。

第一幅的css
