一、关于添加鼠标特效（关于swig渲染）

一）网址

https://blog.csdn.net/qq_42889280/article/details/103087564（鼠标点击特效这个有四种特效，看着挺乖的）

https://blog.csdn.net/yu826103408/article/details/106617947（鼠标移动特效）

二）步骤

1.配置

在主题 _config.yml 中添加动态配置项

1
2
3
cursor_effect:
enabled: true
type: love  # fireworks：礼花 | explosion：爆炸 | love：浮出爱心 | text：浮出文字

在 主题/layout/_layout.swig 中引入

1
{% include '_custom/custom.swig' %}

2.添加代码

/themes/主题/layout/_custom/custom.swig ，添加如下代码：

{% if theme.cursor_effect %}
  {% if theme.cursor_effect.type == "fireworks" %}
    <script src="/js/cursor/fireworks.js"></script>
  {% elseif theme.cursor_effect.type == "explosion" %}
    <canvas class="fireworks" style="position: fixed;left: 0;top: 0;z-index: 1; pointer-events: none;" ></canvas>
    <script src="//cdn.bootcss.com/animejs/2.2.0/anime.min.js"></script>
    <script src="/js/cursor/explosion.min.js"></script>
  {% elseif theme.cursor_effect.type == "love" %}
    <script src="/js/cursor/love.min.js"></script>
  {% elseif theme.cursor_effect.type == "text" %}
    <script src="/js/cursor/text.js"></script>
  {% endif %}
{% endif %}

3.插入js文件

插入到 /themes/主题/source/js/cursor/ 下

1）fireworks.js

二、添加评论功能

一）注册

在来必力网站进行注册，http://livere.com/

注册很方便，有邮箱就可以，选择一般免费的版本就可以。

二）安装

选择免费的版本，安装之后，会弹出来一段代码，选择一般网站内一个框。

三）修改

在主题所对应的_config.yml .进行修改

将来必力所对应的uid处插入刚刚代码中data-uid

四）添加评论的位置

在需要评论模块的地方加入相应ejs文件里

比如要在文章里添加，就在post.ejs里添加

五）部署

部署完看效果
