Millennial

Millennial is a minimalist Jekyll theme for publishing a clean, content-focused blog or publication site, designed to run 100% on GitHub Pages with no local Jekyll installation required.

What is Millennial?

Millennial is an open-source Jekyll theme created by Paul Le that turns Markdown posts and YAML configuration into a static website. It takes content added to the _posts directory plus settings in _config.yml and _data/settings.yml and generates a complete blog or publication site. The theme is built to be fully compatible with GitHub Pages and is distributed under the MIT License with 483 stars on GitHub.

Key Features

• GitHub Pages compatibility — The theme is designed to work directly on GitHub Pages; users can fork the repository and publish by renaming it to USERNAME.github.io.
• Sass/SCSS support — Uses Jekyll's built-in Sass preprocessor (assets/css/main.scss) for easy styling customization.
• Google Analytics integration — Add your Google Analytics ID in _data/settings.yml under google-ID to track site statistics.
• Disqus commenting — Enable comments on posts by setting disqus.comments to true in _data/settings.yml and adding your Disqus shortname.
• MathJax/LaTeX support — Comes bundled with MathJax so you can render mathematical equations in posts using LaTeX syntax.
• RSS feeds — Supports both Atom via the jekyll-feed plugin and RSS 2.0 through the included rss-feed.xml file.
• Social media icons — Font Awesome icons in the footer can be customized via _data/settings.yml.
• Syntax highlighting — Uses Rouge (via fenced code blocks) to color-code source code in posts.

Who is it for?

• Bloggers who want a clean, minimalist layout without distraction — just add Markdown files to _posts and rebuild.
• Technical writers and documentation maintainers who want a simple static site hosted on GitHub Pages with version control.
• Jekyll beginners who want a pre-structured theme and prefer editing via the GitHub code editor rather than installing Jekyll locally.
• Publication editors who need a content-focused site with menu pages, categories, and social sharing.

What can you do with Millennial?

• Publish a personal blog: Write posts in Markdown with YAML front matter (layout, title, author, categories, tags, image) and publish instantly to GitHub Pages.
• Create a documentation site: Use the built-in page layout and menu folder to organize reference pages, with syntax highlighting for code snippets.
• Run a publication or magazine-style site: Use categories and tags to organize articles, plus related posts generation.
• Show a portfolio or project site: Customize the home page (index.html) with Liquid template code to feature selected content.

How does Millennial work?

Installation follows the standard Jekyll workflow: fork the repository (or download and unzip), run bundle install then jekyll serve locally, or push to a gh-pages branch to publish via GitHub Pages. Content is added as posts in _posts with the naming convention YYYY-MM-DD-name-of-post.md, and site-wide settings live in _config.yml and _data/settings.yml. To start from scratch, delete the sample posts in _posts, images in assets/img, and files in pages.

Pros and cons

• Pros: Free and open source (MIT license), zero config for GitHub Pages, includes Disqus, Google Analytics, MathJax, and RSS out of the box, minimalist design that keeps focus on content.
• Cons: The theme is designed as a base for customization; some advanced changes require knowledge of Liquid, SCSS, and Jekyll's directory structure.
