Here is my minimalist css microframework : https://concrete.style

There was a discussion only recently about "no-nonsense" themes for Jekyll et al.: https://news.ycombinator.com/item?id=20266932

Note that people's definitions of what constitutes a minimalist/no-nonsense theme seem to differ, with some emphasizing appearance, others dependencies and elegance of the generated code.

I hope that users can realize that it is not the layout and interface of a blog that can enrich it, but the continuous sharing and high-quality content that never stops updating. That is what minimalist/no-nonsense, we should pay attention to the nature of things and keep moving.
