前言

美化之前

美化的时候需要修改网站的源文件、添加样式、js之类的，需要一点基础，可以参考

Leonus

在添加完js、css后，一定要记得在_config.butterfly.yml的inject里引用

基于butterfly主题的历史上的今天 2.0重置版
小冰博客
小小折腾了一下

一开始就对冰老师的历史上的今天蛮感兴趣的，但是按照两个教程（插件版、源码版）来都不行，我还只是个小趴菜

cdn访问不了

无奈找到了店长的售后群，在群里咨询了大佬

甜梨酱，嘿嘿嘿，我的甜梨酱🤤🤤🤤

了解到要换反代后，就去找了下，于是将源码版教程里的cdn.jsdelivr.net换成了gcore.jsdelivr.net

感谢大佬：记录一些优质的反向代理：反代Jsdelivr、反代Github Raw - 勿埋我心 (skyqian.com)

换完教程里的链接后，结果又报错

js里面的cdn也要换

这里面的访问不了，那我就只能把源码拿下来改改了😓

修改方案

前三段和冰老师的一样，只是后面稍微改了一下

1. 添加card_history.pug

添加[blogRoot]\themes\butterfly\layout\includes\widget\card_history.pug

.card-widget.card-history

       i.fas.fa-clock.fa-spin
       span= _p('那年今日')
    #history-baidu(style='height: 100px;overflow: hidden;')
      #history-container.history_swiper-container(style="width: 100%;height: 100%;")
          #history_container_wrapper.swiper-wrapper(style="height:20px" )

2. 修改index.pug

#aside-content.aside-content
  //- post
  if is_post()
    - const tocStyle = page.toc_style_simple
    - const tocStyleVal = tocStyle === true || tocStyle === false ? tocStyle : theme.toc.style_simple
    if showToc && tocStyleVal
      .sticky_layout
        include ./card_post_toc.pug
    else

      !=partial('includes/widget/card_announcement', {}, {cache: true})
      !=partial('includes/widget/card_top_self', {}, {cache: true})
      .sticky_layout
        if showToc
          include ./card_post_toc.pug

        !=partial('includes/widget/card_recent_post', {}, {cache: true})
        !=partial('includes/widget/card_ad', {}, {cache: true})

    !=partial('includes/widget/card_announcement', {}, {cache: true})

    .sticky_layout
      if showToc
        include ./card_post_toc.pug

      !=partial('includes/widget/card_recent_post', {}, {cache: true})

      !=partial('includes/widget/card_webinfo', {}, {cache: true})
      !=partial('includes/widget/card_bottom_self', {}, {cache: true})

3. 修改_config.butterfly.yml

    category: false
    flink: false # 友链页隐藏侧栏
+  card_history: # 添加开关名称
+    enable: true # 打开card_history开关
  card_author:
    enable: true

4. 引入inject

这里因为cdn.jsdelivr.net访问不了了，所以只需要引入下面的

inject:
  head:
    - <link rel="stylesheet" href="https://gcore.jsdelivr.net/gh/Zfour/Butterfly-card-history/baiduhistory/css/main.css">

  bottom:
    - <script data-pjax type="text/javascript" src="https://gcore.jsdelivr.net/npm/swiper/swiper-bundle.min.js"></script>
