“祝你生日快乐，祝你生日快乐……”，过生日有生日歌，生日蛋糕也是必不可少的，这篇文章主要为大家详细介绍了程序员利用纯HTML5+CSS3制作的生日蛋糕,具有一定的参考价值，感兴趣的小伙伴们可以参考一下
以一个前端开发的身份绘制一个简单的蛋糕庆祝一下今天这个好日子吧，程序员庆生的乐趣与哀愁啊。写的比较简陋，感兴趣的看一下吧。
先发个效果图吧
蛋糕分为三个部分，底部蛋糕，顶层蛋糕和蜡烛部分。HTML的布局结构也是按照这三部分布局的。另外就是使用CSS定位和CSS3的rotate，内外阴影等效果调整部分DOM元素样式。比较简单，相信码农都懂的。
不赘述其它有的没的了。
下面给出完整的的HTML代码和CSS代码
