给你的博客添加一个宠物挂件

看见了石头大佬博客的这个宠物挂件有点心动，于是乎，我也来搞一个。

顶部挂件

如果是其它主题，可以按照下面方法，进行一定修改。。。

如果是安知鱼主题，那么直接替换themes\anzhiyu\layout\includes\bbTimeList.pug文件就行了，代码放下面了

如果你发现夜间模式会被遮挡一部分可以添加下这段css试试，暂且不知道会不会影响其它部分

页脚挂件

挂件基于青桔气球的教程进行修改，适配安知鱼主题。只需在主题中引入以下JavaScript代码，即可在页脚动态插入一个动物挂件。

需要开启 主题配置文件中的footer_bar选项，设置为true

将以下代码直接插入到主题的JavaScript文件中，其他主题可能需要调整插入位置。

1.新建一个footer-animal.js文件，将以下代码粘贴进去。

2.然后在_config.anzhiyu.yml中inject选项的bottom中添加<script src="/static/footer-animal.js" defer></script>。 根据你文件位置，自行调整。
