Nagymaros is a Jekyll theme for conference and event websites, providing four ready-made pages for event details, schedules, maps, and participant directories.
What is Nagymaros?
Nagymaros is a Jekyll theme designed for conferences, workshops, meetings, and similar events. It accepts event data written in YAML files inside the _data folder and generates a static website with four default pages: an index with alerts and external links, a program page with single-day or multi-day schedules and color-coded categories, a map page with customizable markers and tooltips, and a participant list with optional roles, affiliations, and email addresses. The theme is built on Bootstrap 5, uses Inter for body text and Zilla Slab for display headings, and is adapted from jekyll-conference-theme with a focus on simplicity and easier customization. It runs on Jekyll and can be installed as a Ruby gem or by cloning the repository.
Key Features

How does Nagymaros work?
Nagymaros runs as a standard Jekyll site. To install, add gem "jekyll-nagymaros" to your Gemfile and theme: jekyll-nagymaros to _config.yml, then run bundle install. Content is entered as YAML data in the _data folder, and the theme generates the HTML pages from that data at build time. To customize hidden theme files, create new files with the same names and paths in your site directory; Jekyll prioritizes your files during build.
