Papicu is a free, MIT-licensed Jekyll theme for personal blogs that ships with dark mode, KaTeX math rendering, and sidenotes.
What is Papicu?
Papicu is a Jekyll theme created by Lucas R for personal use, built for the static site generator Jekyll. It takes content written in Markdown with YAML front matter and generates a complete static website with a minimalist, content-focused design. The theme is distributed under the MIT License, so it can be used and modified freely. It supports dark mode, KaTeX for mathematical notation, and sidenotes for margin annotations. The project's repository is hosted on GitHub and the demo site is deployed on Netlify, as indicated by a status badge.
Key Features
- Dark Mode — Switches between light and dark color schemes, letting readers choose their preferred appearance.
