Hydure

Hydure is a Jekyll blog theme that arranges content into a two-column layout using the Pure.css CSS framework. It takes a standard Jekyll site — posts, pages, and configuration — and outputs a static blog with a responsive sidebar, dark mode, and integrated publishing features. The theme is maintained by zivong and distributed as a gem named jekyll-theme-hydure, with a demo at zivong.blog/jekyll-theme-hydure.

What makes Hydure stand out?

• Dark mode — Automatically switches to a dark palette via the CSS prefers-color-scheme media query, with no JavaScript required.
• Math support — MathJax is built in; enable it per post by setting math: true in the front matter.
• Comments and analytics — Disqus shortname and Google Analytics 4 Measurement ID are configured through global variables, so readers can comment and traffic is tracked out of the box.
• Archive pages — Year, category, and tag archives are generated in pure Liquid — no plugins needed — by creating a page with layout: archive and a type of years, categories, or tags.
• Pagination and feeds — Includes Jekyll Paginate for splitting post lists and Jekyll Feed for Atom/RSS output.
• SEO support — Jekyll SEO Tag injects meta tags for search engines and social sharing.
• Icons and colors — Font Awesome icons for social links and the Open Color palette for a consistent, accessible color scheme.
• Customization hooks — Navigation is defined in _data/navigation.yml, social links in _data/social.yml, and extra head content can be added via an _includes/custom-head.html file.

Who should use Hydure?

• Jekyll bloggers — Writers who want a clean two-column blog with minimal setup can install the gem and start publishing posts with Markdown.
• Developers — Those comfortable with Jekyll data files can customize navigation, social links, and the page head without editing theme layouts.
• Academics or technical writers — Anyone publishing math-heavy posts can enable MathJax per page to render LaTeX equations.
• GitHub Pages users — Since the theme supports jekyll-remote-theme, hosting on GitHub Pages is straightforward by setting remote_theme: zivong/jekyll-theme-hydure.

What can you do with Hydure?

• Publish a personal blog — Create posts with front-matter options for descriptions, last-modified dates, and multiple authors, and let pagination organize them.
• Build a documentation site — Use archive pages and custom navigation to structure content by year or topic, and add alert messages with the built-in message class.
• Launch a portfolio — The two-column layout with sidebar cover image and social links can present a personal profile plus a blog.
