给安和鱼主题的博客挂上红灯笼

老刘博客2024-07-232026-02-15

今天我们来给安知鱼主题的 Hexo 博客添红灯笼，临近春节的时候，很多小伙伴的博客都开始悬挂红灯笼，喜气洋洋，今天我们来看实现教程。

1.添加信息字段

我们需要对博客根目录下面的 _config.yml 进行字段添加，打开这个文件之后，找一个合适的位置添加以下代码

1
2
3

denglong:
  enable: true  # true 开启 false 关闭
  text: "新年快乐"  # 配置灯笼的四个字

主要设置目的，就是为了方便开启红灯笼，毕竟春节和其他节庆日时间有限，需要祝贺的内容也不相同。

2.添加并引用 CSS

完成了第一步后我们需要为红灯笼进行样式定义。

在博客主题的 /source/ 目录中的 css 文件夹中，创建一个名为 coustom.css 的文件。

在新建的 custom.css 文件中添加如下代码：

/* 新年灯笼🏮 */
.denglong {
    pointer-events: none;
  }
  
  .deng-box1 {
    position: fixed;
    z-index: 9999;
    top: -30px;
    left: -1px;
  }
  
  .deng-box2 {
    position: fixed;
    z-index: 9999;
    top: -25px;
    left: 184px;
  }
  
  .deng-box3 {
    position: fixed;
    z-index: 9999;
    top: -28px;
    right: 11px;
  }
  
  .deng-box4 {
    position: fixed;
    z-index: 9999;
    top: -26px;
    right: 183px;
  }
  
  .deng {
    position: relative;
    width: 120px;
    height: 90px;
    margin: 50px;
    background: rgba(216, 0, 15, 0.8);
    border-radius: 50%;
    transform-origin: 50% -100px;
    animation: swing 3s infinite ease-in-out;
    box-shadow: -5px 5px 50px 4px rgba(250, 108, 0, 1);
  }
  
  .deng:before {
    position: absolute;
    top: -7px;
    left: 29px;
    height: 12px;
    width: 60px;
    content: " ";
    display: block;
    z-index: 999;
    border-radius: 5px 5px 0 0;
    border: solid 1px #dc8f03;
    background: linear-gradient(to right, #dc8f03, #ffa500, #dc8f03, #ffa500, #dc8f03);
  }
  
  .deng:after {
    position: absolute;
    bottom: -7px;
    left: 10px;
    height: 12px;
    width: 60px;
    content: " ";
    display: block;
    margin-left: 20px;
    border-radius: 0 0 5px 5px;
    border: solid 1px #dc8f03;
    background: linear-gradient(to right, #dc8f03, #ffa500, #dc8f03, #ffa500, #dc8f03);
  }
  
  .deng-a {
    width: 100px;
    height: 90px;
    background: rgba(216, 0, 15, 0.1);
    margin: 12px 8px 8px 10px;
    border-radius: 50%;
    border: 2px solid #dc8f03;
  }
  
  .deng-b {
    width: 45px;
    height: 90px;
    background: rgba(216, 0, 15, 0.1);
    margin: -2px 8px 8px 26px;
    border-radius: 50%;
    border: 2px solid #dc8f03;
  }
  
  .xian {
    position: absolute;
    top: -50px;
    left: 60px;
    width: 2px;
    height: 50px;
    background: #dc8f03;
  }
  
  .shui-a {
    position: relative;
    width: 5px;
    height: 20px;
    margin: -5px 0 0 59px;
    animation: swing 4s infinite ease-in-out;
    transform-origin: 50% -45px;
    background: #ffa500;
    border-radius: 0 0 5px 5px;
  }
  
  .shui-b {
    position: absolute;
    top: 14px;
    left: -2px;
    width: 10px;
    height: 10px;
    background: #dc8f03;
    border-radius: 50%;
  }
  
  .shui-c {
    position: absolute;
    top: 18px;
    left: -2px;
    width: 10px;
    height: 35px;
    background: #ffa500;
    border-radius: 0 0 0 5px;
  }
  
  .deng-t {
    font-family: "华文行楷", Arial, Lucida Grande, Tahoma, sans-serif;
    font-size: 3.2rem;
    color: #dc8f03;
    font-weight: bold;
    line-height: 85px;
    text-align: center;
  }
  
  @keyframes swing {
    0% {
      transform: rotate(-10deg);
    }
    50% {
      transform: rotate(10deg);
    }
    100% {
      transform: rotate(-10deg);
    }
  }
  
  /* 适配暗色模式 */
  [data-theme="dark"] .deng {
    background: rgba(216, 0, 15, 0.8);
  }
  
  [data-theme="dark"] .deng-a,
  [data-theme="dark"] .deng-b {
    background: rgba(216, 0, 15, 0.1);
  }
  
  @media screen and (max-width: 768px) {
    .deng-box1,
    .deng-box2,
    .deng-box3,
    .deng-box4 {
      display: none !important;
    }
  }

做好上面的文件之后，在安知鱼主题的配置文件中搜索 inject ，就会找到如下代码

# Inject
# Insert the code to head (before '</head>' tag) and the bottom (before '</body>' tag)
# 插入代码到头部 </head> 之前 和 底部 </body> 之前
inject:
  head:
    # 自定义css
    # - <link rel="stylesheet" href="/css/custom.css" media="defer" onload="this.media='all'">

  bottom:
    # 自定义js
    # - <script src="/js/xxx"></script>

在 head 处进行自定义 css 的引入工作：

1	- <link rel="stylesheet" href="/css/custom.css">

修改完成之后的代码如下

# Inject
# Insert the code to head (before '</head>' tag) and the bottom (before '</body>' tag)
# 插入代码到头部 </head> 之前 和 底部 </body> 之前
inject:
  head:
    # 自定义css
    # - <link rel="stylesheet" href="/css/custom.css" media="defer" onload="this.media='all'">
    - <link rel="stylesheet" href="/css/custom.css">

  bottom:
    # 自定义js
    # - <script src="/js/xxx"></script>
    - <script src="/js/countdown.js"></script>

3.修改 layout.pug文件

紧接着我们需要修改模板引擎 /themes/anzhiyu/layout/includes/layout.pug 文件，这里特别要注意缩进，Pug 的缩进至关重要，它直接决定了代码能否正确运行以及最终生成的 HTML 结构。可是使用下面的代码进行完整替换

- var htmlClassHideAside = theme.aside.enable && theme.aside.hide ? 'hide-aside' : ''
- page.aside = is_archive() ? theme.aside.display.archive: is_category() ? theme.aside.display.category : is_tag() ? theme.aside.display.tag : page.aside
- var hideAside = !theme.aside.enable || page.aside === false ? 'hide-aside' : ''
- var pageType = is_post() ? 'post' : 'page'

doctype html
html(lang=config.language data-theme=theme.display_mode class=htmlClassHideAside)
  head
    include ./head.pug
      if theme.denglong.enable
        - const denglongText = theme.denglong.text || "新年快乐"; // 如果未配置，默认显示“新年快乐”
        .denglong
          each char, index in denglongText
            div(class=`deng-box${index + 1}`)
              .deng
                .xian
                .deng-a
                  .deng-b
                    .deng-t= char
                .shui.shui-a
                  .shui-c
                  .shui-b


  body(data-type="anzhiyu")
    #web_bg
    #an_music_bg
    if theme.preloader.enable
      !=partial('includes/loading/index', {}, {cache: true})
    if (theme.mourn.enable && is_home_first_page())
      include ./mourn.pug
    if page.type !== '404'
      #body-wrap(class=pageType)
        include ./header/index.pug
        main#blog-container
          if (is_home())
            include ./bbTimeList.pug
          if is_current("/")
            include ./top/top.pug
          if page.top_single
            - let background = page.top_single_background
            - let tip = page.top_single_tip
            - let subTitle = page.top_single_subtitle
            - let btn_link = page.top_single_btn_link
            - let btn_text = page.top_single_btn_text
            #single_top
              .author-content.author-content-item.single(style=`${background ? `background: url(${background}) top / cover no-repeat;` : ""}`)
                .card-content
                  .author-content-item-tips=subTitle
                  span.author-content-item-title=page.title
                  .content-bottom
                    .tips=tip
                  .banner-button-group
                    a.banner-button(onclick=`pjax.loadUrl("${url_for(btn_link ? btn_link : '/about')}")`)
                      i.anzhiyufont.anzhiyu-icon-arrow-circle-right(style='font-size: 1.5rem')
                      span.banner-button-text=btn_text ? btn_text : "关于我"

          #content-inner.layout(class=hideAside)
            if body
              div!= body
            else
              block content
              if theme.aside.enable && page.aside !== false
                include widget/index.pug

        - var footerBg = theme.footer_bg
        if (footerBg)
          if (footerBg === true)
            - var footer_bg = bg_img
          else
            - var footer_bg = theme.footer_bg.indexOf('/') !== -1 ? `background-image: url('${url_for(footerBg)}')` : `background: ${footerBg}`
        else
          - var footer_bg = ''

        footer#footer(style=footer_bg)
          !=partial('includes/footer', {}, {cache: true})
        
        if (theme.agreementPopup && theme.agreementPopup.enable && is_home_first_page())
          - let agreementPopupUrl = theme.agreementPopup.url
          script(defer).
            var hasShownPopup = sessionStorage.getItem('sessionNegotiatePopupShown');

            if (!hasShownPopup) {
              setTimeout(() => {
                anzhiyuPopupManager && anzhiyuPopupManager.enqueuePopup('协议提醒助手', '查看本站为你的个人隐私做出的努力', '#{agreementPopupUrl}', 4000);
                sessionStorage.setItem('sessionNegotiatePopupShown', 'true');
              }, 1000);
            }

    else
      include ./404.pug

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

    if theme.shortcutKey.enable
      !=partial('includes/shortcutKey', {}, {cache: true})
    include ./rightside.pug

    if (theme.nav_music.enable || theme.nav_music.console_widescreen_music)
      include ./music.pug
    !=partial('includes/third-party/search/index', {}, {cache: true})
    !=partial('includes/anzhiyu/rightmenu', {}, {cache:true})
    include ./additional-js.pug

    //- 弹窗通知
    !=partial('includes/popup/index', {}, {cache: true})

上面的代码只需要复制粘贴替换掉 layout.pug 文件即可，实际修改的代码并不复杂，在 layout.pug 文件中找到

doctype html
html(lang=config.language data-theme=theme.display_mode class=htmlClassHideAside)
  head
    include ./head.pug

然后在这段代码下面添加

if theme.denglong.enable
  - const denglongText = theme.denglong.text || "新年快乐"; // 如果未配置，默认显示“新年快乐”
  .denglong
    each char, index in denglongText
      div(class=`deng-box${index + 1}`)
        .deng
          .xian
          .deng-a
            .deng-b
              .deng-t= char
          .shui.shui-a
            .shui-c
            .shui-b
