Gesko

Gesko is a minimalist, responsive Jekyll blog theme that generates a static site with built-in search, dark/light mode, and reading-time estimates.

What is Gesko?

Gesko is a simple and minimal Jekyll blogging theme, forked from Asko and built on the Sidey theme by Ronv. It takes standard Jekyll content—Markdown posts and configuration—and produces a static HTML blog with features like tag pages, feeds, and a 404 page. The theme is maintained by DavideBri and is released under the MIT License.

Key Features

• Responsive design — the layout adapts to mobile and desktop screens without additional JavaScript.
• Dark/light theme — a toggle lets readers switch between light and dark color schemes.
• Built-in search bar — a client-side search box for finding posts without an external service.
• Tag pages — automatically generate a page per tag by adding a folder under the tag directory; the theme then lists all posts with that tag.
• Reading time estimation — displays estimated reading time per post, configurable between automatic and manual modes.
• Atom and JSON feeds — subscribable feeds are generated for syndicating blog updates.
• Next/Previous post navigation — links at the bottom of each article let readers move chronologically through the archive.
• Disqus comments (optional) — an optional integration that can be enabled or disabled per site.
• Sass styling — the theme compiles styles with Sass, and it passes PageSpeed and w3Validator tests per the project readme.
• Inline CSS — styles are inlined in the head for faster initial render.

Who is it for?

Gesko is for bloggers and developers who want a no-frills Jekyll theme that loads quickly and ranks well in performance tests. It suits personal blogs, portfolios, or documentation sites where a clean reading experience matters more than visual clutter.

What can you do with Gesko?

• Personal bloggers: publish Markdown posts and automatically get tag archives, search, and feed subscriptions.
• Developers: host the generated static site on GitHub Pages for free, and customize the theme with Sass and Jekyll includes.
• Technical writers: use the built-in reading time and anchor headings to create long-form documentation that is easy to navigate.

How does Gesko work?

Installation follows the standard Jekyll workflow: clone the repository, run bundle install, then build or serve with bundle exec jekyll build or bundle exec jekyll serve. To add a custom tag, create a folder in the tag directory with an index.html file that sets the layout to tag and specifies the tag name; the theme then generates a dedicated listing page for that tag.

Pros and cons

Pros: completely free (MIT), fast and lightweight due to inline CSS, passes PageSpeed and w3Validator checks, and supports dark mode.

Cons: the default layout includes a Google tag (gtag) that must be removed by hand, and you must update the site url and baseurl settings in _config.yml before deploying to GitHub Pages.

Pricing

Gesko is open-source and free to use under the MIT License.
