Blackboard is a Ghost theme which I created for this blog.
I like minimalist designs and I've hopped from different themes trying to find the perfect settings in the past; after I moved my blog to Ghost. In the end I decided to follow the Ghost theme development documentation and learned a few things about Tailwind CSS.
I am doing further development of the theme in the open and hence the code is available on GitHub. Feel free to peek inside, comment and/or improve it.
