最近在抖音中有着很火的一个有关于“前端情人节纪恋日计时功能案例详解！”这方面的相关案例，那么今天小编就来带大家下实现这个梦想！
前言
利用HTML5，css，js实现爱心树 以及 纪念日期的功能 网页有播放音乐功能 以及打字倾诉感情的画面，非常适合情人节送给女朋友
具体的HTML代码
具体只要修改代码里面的男某某和女某某 文字段也可自行修改，还有代码下半部分的JS代码需要修改一下起始日期 注意月份为0~11月 也就是月份需要减一。
当然只有一部分HTML和JS代码不够运行的，文章最下面还附加了完整代码的下载地址：

<iframe src = "./给你们.mp3" allow = "autoplay" hidden /> //自己修改音乐位置
</body>
</html>画面演示：
①点击网页中心的爱心，刚进入网页会自动播放音乐
②会慢慢生成爱心树，速度挺快的
③然后会平移爱心树到最右边，准备生成文章
④会慢慢生成所要说的话 日期设定是2020.02.02 22：22：22
⑤最后的样子
