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 |
|---|
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
