XMin is a Hugo theme written by Yihui Xie in about four hours: half an hour was spent on the Hugo templates, and 3.5 hours were spent on styling. The main motivation for writing this theme was to provide a really minimal example to beginners of Hugo templates. This XMin theme contains about 130 lines of code in total, including the code in HTML templates and CSS (also counting empty lines).

I can certainly further reduce the code, for example, by eliminating the CSS, but I believe a tiny bit CSS can greatly improve readability. You cannot really find many CSS frameworks that only contain 50 lines of code.
