Helium is a fast, modern, and configurable Bootstrap 4 based Jekyll theme for blogs, featuring hero images with colored overlays, a live theme switcher, and built-in support for tags and link posts.
What is Helium Jekyll?
Helium Jekyll is a static-site theme for Jekyll 3.x, created by Antonio Trento and built on the Helium UI Kit for Bootstrap 4. It converts Jekyll posts written in Markdown with YAML front matter into a blog layout with prominent hero images, colored overlays, and smooth animations. The theme is fully compatible with GitHub Pages and is released under the MIT license, making it free to use, modify, and redistribute.
Key Features
- Bootstrap 4 and Font Awesome — Built on Bootstrap 4 (specifically the v4-alpha version linked in the README) and includes Font Awesome icons, giving you a responsive grid and a set of 100+ UI blocks from the Helium UI Kit.
- Hero images with overlays — The main blog layout displays hero images for each post, with colored overlays and animations. The Liquid code that appends the correct hero image and overlay color is in
include/utils/hero.html. - Live theme switcher — A live theme switcher lets visitors change the theme in the browser without reloading the page.
- Jekyll 3.x and GitHub Pages compatibility — Fully compatible with Jekyll 3.x and GitHub Pages. Deploy by forking the repo, renaming it to
yourusername.github.io, and editing_config.ymlwith your details. - SEO optimized — The theme comes with SEO optimization built in, so your posts are more likely to appear in search results.
- Google Analytics and AdSense support — Configure Google Analytics for traffic tracking and Google AdSense for advertising through
_config.yml. - Disqus comments — Built-in Disqus support lets readers comment on your posts without a custom commenting system.
- Tags and link posts — Tags and tag pages are generated using Jekyll's native collections, and link posts are supported for sharing external URLs.
