安装

在 Hexo 根目录里

1
git clone -b master https://github.com/jerryc127/hexo-theme-butterfly.git themes/butterfly

应用主题

修改 Hexo 根目录下的 ，把主题改为 _config.ymlbutterfly

1
theme: butterfly

安装插件

如果没有 pug 以及 stylus 的渲染器，下载安装：

1
npm install hexo-renderer-pug hexo-renderer-stylus --save

主题配置

主题配置文件是themes/butterfly/_config.yml

导航目录

设置顶部右上方区域的内容

# Menu 目录
menu:
  首页: / || fas fa-home
  归档: /archives/ || fas fa-archive
  标签: /tags/ || fas fa-tags
  分类: /categories/ || fas fa-folder-open
  友链: /link/ || fas fa-link
  关于: /about/ || fas fa-heart
# 格式如下：
# [标题]: [路径] || [图标]

这里的目录中，tags、categories、link、about目录默认不存在，需要在Bash窗口中使用命令生成对应页面

hexo new page tags
hexo new page categories
hexo new page link
hexo new page about

把创建的页面设置为对应的页面类型

代码高度限制

可配置代码高度限制，超出的部分会隐藏，并显示展开按钮。

1
highlight_height_limit: false # unit: px

注意：
单位是px，直接添加数字，如 200
实际限制高度为highlight_height_limit + 30 px ，多增加 30px 限制，目的是避免代码高度只超出highlight_height_limit 一点时，出现展开按钮，展开没内容。
不适用于隐藏后的代码块（ css 设置 display: none）

页脚自定义文本

custom_text是一个用来在页脚自定义文本的选项。通常可以在这里写声明文本等。支持 HTML。

修改主题配置文件_config.butterfly.yml。

页脚如下，若在配置时没有出现github徽章，请参考教程添加Github徽标.

custom_text: I wish you to become your own sun, no need to rely on who's light.<p><a target="_blank" href="https://hexo.io/"><img src="https://img.shields.io/badge/Frame-Hexo-blue?style=flat&logo=hexo" title="博客框架为Hexo"></a>&nbsp;<a target="_blank" href="https://butterfly.js.org/"><img src="https://img.shields.io/badge/Theme-Butterfly-6513df?style=flat&logo=bitdefender" title="主题采用butterfly"></a>&nbsp;<a target="_blank" href="https://www.jsdelivr.com/"><img src="https://img.shields.io/badge/CDN-jsDelivr-orange?style=flat&logo=jsDelivr" title="本站使用JsDelivr为静态资源提供CDN加速"></a> &nbsp;<a target="_blank" href="https://vercel.com/ "><img src="https://img.shields.io/badge/Hosted-Vervel-brightgreen?style=flat&logo=Vercel" title="本站采用双线部署，默认线路托管于Vercel"></a>&nbsp;<a target="_blank" href="https://vercel.com/ "><img src="https://img.shields.io/badge/Hosted-Coding-0cedbe?style=flat&logo=Codio" title="本站采用双线部署，联通线路托管于Coding"></a>&nbsp;<a target="_blank" href="https://github.com/"><img src="https://img.shields.io/badge/Source-Github-d021d6?style=flat&logo=GitHub" title="本站项目由Gtihub托管"></a>&nbsp;<a target="_blank" href="http://creativecommons.org/licenses/by-nc-sa/4.0/"><img src="https://img.shields.io/badge/Copyright-BY--NC--SA%204.0-d42328?style=flat&logo=Claris" title="本站采用知识共享署名-非商业性使用-相同方式共享4.0国际许可协议进行许可"></a></p>

对于部分人需要写 ICP 的，也可以写在custom_text里。

页面加载动画preloader

当进入网页时，因为加载速度的问题，可能会导致top_img图片出现断层显示，或者网页加载不全而出现等待时间，开启preloader后，会显示加载动画，等页面加载完，加载动画会消失。

由于 Hexo 4.1 开始，默认对网址进行解码，以至于如果是中文网址，会被解码，可设置 decode: true 来显示中文网址。

如果有文章（例如：转载文章）不需要显示版权，可以在文章页 Front-matter中单独设置。

阅读模式

阅读模式下会去掉除文章外的内容，避免干扰阅读。只会出现在文章页面，右下角会有阅读模式按钮。

修改主题配置文件_config.butterfly.yml。

inject:

       - <script src="https://cdn.jsdelivr.net/gh/xiabo2/CDN@latest/fishes.js"></script>

有时候会遇到cdn解析失败，导致鱼塘加载不出来，可以js文件格式本地引入

在 source 目录下新建一个 styles 文件夹，用于存放相关文件
添加如下两个文件

文件一：fish-base.js

fish();
function fish() {
    return (
      $("#footer-wrap").css({
        position: "absolute",
        "text-align": "center",
        top: 0,
        right: 0,
        left: 0,
        bottom: 0,
      }),
      $("footer").append(
        '<div class="container" id="jsi-flying-fish-container"></div>'
      ),
      $("body").append(
        '<script src="/styles/fish-base.js"></script>'
      ),
      this
    );
  }
在主题配置文件下引入这两个文件

代码如下：

1
- <script src="/styles/fish.js"></script>

一样也得引入 jquery：

1
- <script src="https://cdn.bootcss.com/jquery/3.4.1/jquery.min.js"></script>

渐变色设置

在styles目录下新建一个 main.css 文件，键入以下代码：

这里只修改了鱼塘和部分个人主页的渐变色，也可以自己调成你喜欢的渐变色

同样，也需要在主题配置文件中引入这个css文件：

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