前言
我是歌谣 我有个兄弟 巅峰的时候排名c站总榜19 叫前端小歌谣 曾经我花了三年的时间创作了他 现在我要用五年的时间超越他 今天又是接近兄弟的一天人生难免坎坷 大不了从头再来 歌谣的意志是永恒的 放弃很容易 但是坚持一定很酷
导语
歌谣 歌谣 新的一年就要到了 你一定有很多想许下的愿望吧 类似于许愿墙这种的,可以实现一下吗 说时迟 这是快 就开始了许愿墙的一个制作 耗时.....不断改造...升级...当然还可以更好,其他就靠兄弟们自由发挥了
效果预览
功能要点介绍
1雪花飘落的代码是js控制的,可自行修改
2许愿墙的贴纸是for循环控制的,可自行修改
3文字是datas数组控制的,可以自行修改
