Jekyll Cayman Theme

Jekyll Cayman Theme is a Jekyll port of Jason Long's Cayman theme, a clean, responsive theme built for GitHub Pages. This template takes a standard Jekyll site structure and produces a mobile-friendly static website that can be hosted on GitHub Pages or any Jekyll-compatible host.

What is the Jekyll Cayman Theme?

The Jekyll Cayman Theme is an open-source Jekyll theme forked from the classic Cayman theme by Jason Long. It is distributed on GitHub at pietromenna/jekyll-cayman-theme and can be downloaded as a ZIP archive, unzipped, and run as a regular Jekyll folder. The theme is designed for GitHub Pages, where it is also available as an option in the Automatic Page Generator. It is licensed under the Creative Commons Attribution 4.0 International license.

Key Features

• Responsive layout — The theme adapts to screen sizes from mobile phones to desktop monitors, matching the Cayman design.
• GitHub Pages ready — Works out of the box with GitHub Pages' Automatic Page Generator or as a manual Jekyll site.
• Standard Jekyll structure — Uses the conventional Jekyll folder layout with _config.yml, so pages, posts, and data files behave normally.
• Configurable baseurl — A baseurl option in _config.yml lets you host the site under a subpath like https://pietromenna.github.io/jekyll-cayman-theme.
• Live preview for development — Running bundle exec jekyll serve starts a local server at http://localhost:4000 and auto-regenerates on changes.
• Contribution-friendly — The repository welcomes bug reports and pull requests, and the theme setup is described as a normal Jekyll site for testing modifications.

Who is it for?

• GitHub Pages users — A straightforward way to publish a project documentation site or personal page with a proven, clean design.
• Jekyll beginners — Because the theme is a self-contained Jekyll site, it serves as a learning example for how Jekyll projects are structured.
• Open-source maintainers — Use it to quickly create a documentation page that matches the look of the original Cayman theme used on many GitHub Pages sites.

What can you do with the Jekyll Cayman Theme?

• Document a software project — Deploy a documentation site to GitHub Pages with no server-side dependencies beyond Jekyll itself.
• Create a personal landing page — Show a short bio, links, and a simple layout without custom CSS work.
• Experiment with Jekyll development — Use the theme as a base to test new pages, layouts, and includes, since it behaves like any normal Jekyll site.

How does the Jekyll Cayman Theme work?

Start by downloading the theme ZIP from the GitHub repository and unzipping it. Then run bundle install to pull the required gems, followed by jekyll serve to launch a local server. For deployment, set the baseurl in _config.yml if the site will live under a subpath, and push the contents to GitHub Pages.
