前言

一年一度的圣诞节马上就要到了，看到好多程序员小伙伴已经开始炫耀自己制作的圣诞树了。今天就跟大家分享2种不同风格的圣诞树，附上完整代码，拿来即用可以按照自己的喜好来去运行使用哦。

一、可以改名字的圣诞树

大家可以在圣诞快乐这里改成自己需要的字，比如名字或者其他的祝福语。

\"\"

怎么改中间的名字呢？

找到代码182行的 圣诞快乐 去改成你需要的文字内容即可

\"\"

 1、下面是完整的代码展示，是HTML哈，运行起来也很方便。

前言

一、可以改名字的圣诞树

 1、下面是完整的代码展示，是HTML哈，运行起来也很方便。

2、添加音乐

二、插画风圣诞树：

1.下面是完整代码展示，可以用Python运行。

总结

2.1 之后是可以自己选择音乐的

\"\"

 第五个选项是自定义音乐，可以挑选你电脑上任意Mp3文件。

2.2选好音乐后稍等片刻就进入下一个页面，播放音乐和圣诞树特效。

\"\"

二、插画风圣诞树：

运行后图片展示：
