This is a theme I personally use.
The wordpress theme Allium, and here is its home page. I like this theme very much when I'm using wordpress, but I don't have it on hugo, so I try my best to write a theme similar with it. There are many designs in this theme refers to it.
The hugo theme jane and mini, this is my first time to write a hugo theme, I referred this two themes' project structure and way of handling problems.
