页脚跳动的心 ​

  1. 修改themes\butterfly\layout\includes\footer.pug文件，加个爱心图标
diff
- .copyright!= `©${nowYear} by ${config.author}`
+ .copyright!= `&copy;${nowYear} <i id="heartbeat" style="color:#FF6A6A" class="fa fa-heartbeat"></i> ${config.author}`
  1. 挂载 CSS，使其动起来，如果用了上面的动态图标可以跳过这一步
CSS

  1. 引入jquery
yml
inject:
  head:
  bottom:
    - <script src="https://cdn.bootcdn.net/ajax/libs/jquery/3.7.1/jquery.min.js"></script>
    - <script src="/js/fish.js" data-pjax></script>
  1. 引入fish.js，如果开启了pjax需要添加data-pjax属性
js
