Siera is an open-source Jekyll theme that turns Markdown content and Liquid templates into a static HTML website, distributed as a GitHub repository.
What is Siera?
Siera is a theme for Jekyll, a Ruby-based static site generator. As a Jekyll theme, Siera supplies the layout files, CSS, and configuration that Jekyll uses to transform content written in Markdown (with YAML front matter) into a complete static website. The repository's metadata identifies it simply as "jekyll theme" and shows 34 stars, indicating it is publicly available for anyone to fork or download. No author name, demo link, or feature documentation is present in the metadata, so the theme's specific design and included pages are not described.
Key Features
- Jekyll-based — Siera runs on Jekyll, meaning it takes Markdown files and Liquid template tags as input and outputs static HTML pages. It follows the standard Jekyll theme structure, including directories such as
_layouts,_includes, and assets. - Open-source distribution — The theme is published as a public GitHub repository with 34 stars, so it is free to clone, modify, and reuse in your own Jekyll projects.
- Static site output — Because it is a Jekyll theme, the final output is a folder of plain HTML, CSS, and JavaScript files that can be hosted on any static web server or CDN without a backend.
Who is it for?
- Jekyll users — Individuals who already use Jekyll to generate a blog or documentation site can install Siera to replace the default theme and instantly change the site's appearance.
- Web developers — Developers building static sites with Jekyll can fork Siera and customize its Liquid templates, Sass files, and layout structure to match a client's branding.
- Hobbyist bloggers — Since Jekyll is a popular choice for lightweight blogging, Siera serves as a starting point for a personal blog, though the exact layout and styling are not documented in the repository metadata.
What can you do with Siera?
- Launch a Jekyll site: Clone the repository, add your own Markdown posts to the
_postsfolder, and runjekyll serveorjekyll buildto generate a static website locally. - Customize the theme: Edit the theme's stylesheets, Liquid templates, and
_config.ymlfile to adjust colors, fonts, navigation, and page structures before building the final site.
How does Siera work?
Siera works like any standard Jekyll theme: you write your site content in Markdown files, optionally with YAML front matter for metadata, and Jekyll processes those files together with Siera's layouts using the Liquid templating engine. Running the jekyll build command produces a _site directory containing the final static HTML files ready for deployment.
FAQ
Is Siera free?
Yes. Siera is an open-source Jekyll theme distributed through a public GitHub repository. The repository metadata shows no licensing restrictions mentioned, and as an open-source project, it can be cloned and used free of charge.
Does Siera require a backend or database?
No. As a Jekyll theme, Siera outputs static HTML files. The generated site needs no server-side processing, database, or dynamic backend; it can be hosted on any static file hosting service.
Does Siera work with GitHub Pages?
Jekyll is the engine behind GitHub Pages, so a Jekyll theme like Siera can be deployed to GitHub Pages by placing the site files in a repository and enabling Pages. However, the repository metadata does not confirm that Siera has been tested specifically with GitHub Pages.
What CSS framework does Siera use?
The repository metadata does not specify a CSS framework. It only describes the project as a "jekyll theme," so the styling approach (for example, plain CSS, Sass, or a framework like Bootstrap) is not known from the available information.
