本次主题使用的是Next 主题，主要是因为这个主题比较简洁。
直接从git上获取主题方法：
Installation If you're using Hexo 5.0 or later, the simplest way to install is through npm:
$ cd hexo-site
$ npm install hexo-theme-next
Or you can clone the entire repository:
$ cd hexo-site
$ git clone https://github.com/next-theme/hexo-theme-next themes/next
See detailed installation instructions if you want any other variant.
After the installation, open Hexo config file and set theme variable to next.
theme: next
