最近阿锋在超市排队买菜（辣条）
一个大叔一边给孩子买吃的一边说：
这些都是增加记忆力的，对孩子好！
蓝莓，深海鱼，全麦面包，坚果儿，十六个核桃······
不禁感叹现在的孩子们还真是幸福啊！
我记得我小时候要记住一件事情
只需：我爸的一巴掌！
高端的记忆方法，往往只需要最朴素的操作手段
果然啊~~大道至简
那在整个计算机行业里
什么语言最简单？CSS！
如果它能算作语言的话（手动狗头保命）
最神奇的语言是什么？CSS！
最玄学，最神奇的也莫过于CSS！
学习两个半月前端信心满满在简历上写着：精通CSS
学习两年半前端轻车熟路的写上：熟练CSS
学习五年前端小心翼翼写上：了解CSS
你不信，你来看这几个动效怎么做？
我们来浅读一下大神们的实现代码：

</html>最后一个动效的源码奉上啦！
（篇幅关系，就不把所有的源码都放上啦！有需要的来找阿锋要哦！）
看完这些动效是不是有些感触？
感触一：卷这些东西意义何在？
感触二：这些动效能够带来一个客户吗？
感触三：我花一周做出来了，其他的需求怎么办？
充满了没用的苹果味儿
但是能写出这些效果来的人对于CSS的掌握程度是毋庸置疑的！
而对于一件事物的了如指掌
总是能让你尝试不同的新方法新姿势！
总是能给人带来不一样的快乐！
想要其他动效源码的！可以直接私信我！
