修改[BlogRoot]\themes\butterfly\layout\includes\post\post-copyright.pug,直接复制以下内容替换原文件内容。此处多次用到了三元运算符作为默认项设置，在确保有主题配置文件的默认项的情况下，也可以在相应文章的front-matter中重新定义作者，原文链接，开源许可协议等内容。

修改[BlogRoot]\themes\butterfly\source\css\_layout\post.styl,直接复制以下内容，替换原文件，这个文件就是自己调节样式的。其中，184行是白天模式的背景色，这里默认是我网站的渐变色，大家可以根据自己的喜好调节；253行是夜间模式的发光光圈颜色，大家也可以自行替换成自己喜欢的颜色：
