CSS动画的毕业设计

用CSS动画写一个七龙珠，据说善良的程序员可以看到龙神，并许愿成功

动画的基本属性和参数

W3C的说法过于笼统，比较难以理解。大家可以简单的记忆为：

我 @keyframes 一个动画，动画的名字叫 play,现在我想让谁动，就把play交给谁。
我把play递给了img，img伸出双手接住了我的play，animation 就是img的双手。

img接过play以后，想了一会儿(延迟)，甩了一下，产生了速度(ease-in-out),他发疯似的一直甩(infinite),甩累了，不动了(forwards)

例如：

@keyframes darken {
  from {
   opacity: 0;
  }
  to {
   opacity: 1;
  }
}

我定义了一个动画，让透明度由0变为1

animation: color 2s infinite;

我开始调用这个动画，效果如下:


可以看出动画十分突兀，喜欢美感的程序员会把from–to替换成百分比，如下：

@keyframes color{
    0%{opacity: 0}
    50%{opacity: 1}
    100%{opacity: 0}
  }
这样动画就柔和很多了


接下来让我们用刚刚学到的新知识做一个小案例吧

老样子，先给源码
