一、前言
备注：
- 整体圣诞树分为3个部分，书的主干、粒子特效、树上的卡片
- 树上的卡片(重点)：每一张卡片上都有一个名字，代表圣诞树的叶子，后面可以根据自己需求更改，比如全部改成喜欢人的名字，在JS代码的第五行内更改内容
- 树的动态旋转通过js实现、主干是html5、样式CSS
三、步骤
1.下载VSCode
VSCode
- 在Hbuilder、idea运行也是可以的，这里推荐使用VSCode
2.配置插件
文件名字要和这个一样，不然会出错），保存别忘了
4.添加额外功能
修改背景：
修改卡片上的内容： CSS代码： Html代码： JS代码： 附录： 原文地址：https://blog.csdn.net/qq_53673551 版权声明：本文内容由互联网用户自发贡献，该文观点与技术仅代表作者本人。本站仅提供信息存储空间服务，不拥有所有权，不承担相关法律责任。如发现本站有涉嫌侵权/违法违规的内容， 请发送邮件至 dio@foxmail.com 举报，一经查实，本站将立刻删除。
