魔改日记（3）

魔改前须知

  1. 魔改有风险，记得备份。
  2. 魔改参考：akilar | Fomalhaut🥝 | 安知鱼 …，更多人请到 友链寻找)（全是大佬）。本文仅做一个好用的魔改总结，便于自己查找。
  3. 鉴于每个人的根目录名称都不一样，本帖 博客根目录 一律以[BlogRoot]指代。
  4. 涉及魔改源码的内容，会使用diff代码块标识，复制时请不要忘记删除前面的+、-符号。
  5. 引入 自定义的css与js文件，方法见 Hexo博客添加自定义css和js文件
  6. themes/butterfly 等同于 /node_modules/hexo-theme-butterfly

新年倒计时卡片

详见：博客新年倒计时卡片 | Leonus

1）新建 [Blogroot]\source\_data\widget.yml 文件，在文件中加入如下代码

建议查看butterfly官方文档：自定义侧边栏

      <div class="newYear-time"></div>
      <p class="today" style="text-align: right;"></p>
      </div>'

2）在 [BlogRoot]\source\css\custom.css 增加如下代码：

4）修改_config.butterfly.yml,添加音频文件配置项，添加CDN配置项：

  # Sponsor/reward

    QR_code:

5）现在的打赏按钮样式需要稍作适配，当前若提示语太长，悬停时会无法显示完全。需要微调一下,修改[Blogroot]\themes\butterfly\source\css\_layout\reward.styl，整体替换为以下内容：
