Time Machine

Time Machine is a free, open-source Jekyll theme for GitHub Pages that generates a static website with a retro time-machine visual style, designed for rapid setup via the remote_theme mechanism.

What is Time Machine?

Time Machine is a Jekyll theme maintained in the pages-themes organization on GitHub and distributed as both a Ruby gem (jekyll-theme-time-machine) and a remote theme. It consumes a standard Jekyll site's configuration and content and outputs a static HTML site styled with a distinctive time-machine aesthetic. It is one of several ready-made themes that GitHub Pages users can adopt by adding a remote_theme line to their site's _config.yml, and it is available for live preview at pages-themes.github.io/time-machine.

What makes Time Machine stand out?

• Remote theme installation — Add remote_theme: pages-themes/time-machine@v0.2.0 to your site's _config.yml (along with the jekyll-remote-theme plugin) to use the theme without forking its repository.
• Configurable metadata — Set title and description in _config.yml to populate the site's header and HTML meta tags.
• Optional download button — The show_downloads variable controls whether the layout displays a URL for downloading the project.
• Google Analytics support — Drop in a tracking ID via the google_analytics variable, or paste custom analytics snippets into _includes/head-custom-google-analytics.html.
• Customizable stylesheet — Create /assets/css/style.scss in your site, import the theme's base styles, and append your own CSS or Sass.
• Layout overrides — The default layout in _layouts/default.html can be copied into your site and changed; the theme's _includes provide a starting point for tweaks like a custom favicon.
• URL override capability — Default GitHub-provided URLs (like repository or zip download links) can be replaced by defining your own under the github key in _config.yml.
• Local preview and tests — Run script/bootstrap and bundle exec jekyll serve to preview the theme locally; script/cibuild runs a minimal test suite in CI.

Who should use Time Machine?

• GitHub Pages beginners — Get a live site in minutes by setting remote_theme and writing Markdown.
• Developers building project sites — Use the theme as a clean, retro-styled base for documentation, portfolios, or personal hubs tied to a GitHub repository.
• Theme contributors — Fork the repository, run the local preview, and follow the CONTRIBUTING guide to propose changes.

What can you do with Time Machine?

• Create a personal website — Configure your title and description, add content in Markdown, and publish to GitHub Pages with the time-machine look.
• Build a project landing page — Set show_downloads so visitors can download a zip or release archive of your project.
• Learn Jekyll theming — Study the theme's layout and includes to understand how a Jekyll theme is structured, then copy or adapt it for your own custom theme.

How does Time Machine work?

To install, you add two items to your site's _config.yml: a remote_theme line pointing to pages-themes/time-machine@v0.2.0, and a plugins list that includes jekyll-remote-theme. On the next build, GitHub Pages fetches the theme and applies its layouts and styles to your content. For local development, you add gem "github-pages" to your Gemfile and run bundle exec jekyll serve.
