According to Jim

I’m sick of WordPress so I wrote a new theme to make it worse

In an attempt to have a WordPress theme optimized for running on the Raspberry Pi 3, I went through the hurdles of writing my own theme. Among my goals was to create something entirely free of third party CSS and JavaScript frameworks. Actually, I wanted a theme free from JavaScript altogether and in my opinion there are already more than enough websites built on the Bootstrap framework (you’ll recognize them, they all look the same).
