最近随着电视剧《点燃我温暖你》的火热播出，剧中帅气学霸李洵的炫酷爱心代码也迅速火出了圈，作为一个喜欢动手实践的我来说正是一个大好机会啊，于是我就把代码搬到了自己的网站上，源码我也放在了我的GitHub上，大家有需自取哦~💗
仓库地址：『https://github.com/huawuque404/Love-code』
也欢迎大家star Issues fork 并pr哦，一起来开发更多好看的样式或者动态效果吧！
网站效果：『https://www.huawuque404.cn/love.html』
后面有时间的话我会将各式各样的爱心代码更新在这个仓库里，如果大家感兴趣的话就来和我一起创造爱心吧~😍
今天周末了，大家都要好好吃饭，好好睡觉哦！🎉
拜拜！
GitHub进不去的话，源代码这也有一份，有点长：
