【圣诞节特辑】爱心代码（程序员的浪漫plus+）-李峋
2022年圣诞节到来啦，很高兴这次我们又能一起度过~
唯有热爱，可抵岁月漫长，唯有热爱，不畏世间无常！
一、前言
前段时间《点燃我温暖你》中李峋的爱心代码超级火，看着特别心动！这不，圣诞节快到了，准备给爱心代码来个plus版本！！！充满惊喜的！！！并且很简单！！！
二、创意设计
1、HTML爱心代码
2、添加登陆页面（必须输入正确的密码才能看到~~~///(^v^)\\\~~~）
3、页面跳转
4、好看的CSS样式
三、效果展示
Plus+
Plus++
包含音乐插件 背景图 自由输入添加文字 
四、代码实现
index.html
登陆页面
初始用户名：root
初始密码：root
可以根据需要自由更改😄
