Future Imperfect Slim

Future Imperfect Slim is a Hugo theme for multilingual blogging that reworks the classic Future Imperfect design with a mobile-first CSS Grid layout, Staticman-powered comments, and modern Hugo functions. It is maintained by Patrick Collins and others as a continued development of jpescador's Hugo port of HTML5 UP's Future Imperfect theme.

What is Future Imperfect Slim?

Future Imperfect Slim is a Hugo blog theme that takes Markdown content files and renders them into a static website. It extends the original hugo-future-imperfect port by restructuring it under newer Hugo functions, slimming the CSS and JS assets, and adding multilingual support. The theme includes an exampleSite directory with sample content and config.toml to help new users start.

Key Features

Future Imperfect Slim packs a set of features that distinguish it from the original hugo-future-imperfect port.

• Multilingual support — Content can be written in multiple languages; the example site includes French, Polish, and Portuguese translations of core pages.
• Staticman comments — The theme can be configured to use Staticman for static, Git-based comments by copying staticman.yml to the project root.
• CSS Grid layout — The layout is built mobile-first using CSS Grid, replacing older float-based frameworks to simplify styling.
• Modern Hugo functions — Hugo asset pipelines and newer functions are used, resulting in slimmer CSS and JS files than the original port.
• Custom JS and CSS — Users can override styling by editing add-on.css and add-on.js, or load additional files via cssFiles and jsFiles settings in config.toml.
• Extra shortcodes — Besides native Hugo shortcodes, the theme documents additional shortcodes on its wiki page.
• Git submodule workflow — The theme is designed to be added as a git submodule, with updates pulled via git submodule update --remote --merge.

Who is it for?

Future Imperfect Slim suits Hugo users who want a personal or group blog with a classic, content-focused design. Multilingual bloggers can publish the same content in several languages without duplicating site structure. Developers who want to customize a theme benefit from the project-level override approach prescribed by Hugo's lookup order. It also fits people coming from HTML5 UP's Future Imperfect who want that look on the Hugo static site generator.

What can you do with it?

With Future Imperfect Slim you can run a multilingual blog with static comments and a customizable front end.

• Start a blog quickly: Copy the exampleSite files, run hugo server, and get a local preview at localhost:1313.
• Publish multilingual posts: Write individual markdown files per language (for example, emoji-support.fr.md alongside emoji-support.md) and Hugo outputs language-specific pages.
• Add static comments: Configure Staticman with the included staticman.yml so visitors can leave comments that are stored as Git-committed JSON files.
• Customize appearance: Replace the add-on CSS/JS files or add your own assets through the config.toml parameters to change colors, fonts, and scripts.

How does it work?

The theme is installed either as a git submodule or by cloning the repository. Users copy config.toml and optionally staticman.yml from the exampleSite directory to the root of their Hugo project, then run the hugo server command to build and preview the site. Customization is done by creating matching template files in the project's layouts folder, which Hugo's lookup order resolves before the theme's own files.

Pros and cons

The theme has a few trade-offs compared with the original port.

• Pro: The theme is actively maintained as a separate repository from the original, which had become stale.
• Pro: The redesign strips unused CSS and JS, resulting in a slimmer bundle.
• Con: The redesign is not directly compatible with previous versions of the original hugo-future-imperfect theme, so upgrades may require adapting templates.

Alternatives

The main alternative is the original hugo-future-imperfect theme that this project derives from.

• hugo-future-imperfect — The original port by jpescador that this theme is based on, which has a different, non-slim structure and lacks the CSS Grid modernization and multilingual overhaul.

FAQ

Does Future Imperfect Slim support multiple languages?

Yes. The theme includes multilingual functionality with example content in French, Polish, and Portuguese, and it was developed through a major overhaul by StatnMap to enable translated pages.

Can I use Staticman comments with this theme?

Yes. Copy the staticman.yml file from exampleSite to your project root, configure it as documented on the wiki, and the theme will support static, Git-backed comments.

How do I update the theme?

If you installed it as a git submodule, run git submodule update --remote --merge from your site's root directory. This will fetch the latest version of the theme repository.

Is this theme compatible with the original Hugo Future Imperfect?

No, not directly. The redesign is not directly compatible with previous versions of the original hugo-future-imperfect, which is why it now lives in its own repository.

Can I customize the theme files?

Yes. Create duplicate files at the project level rather than editing theme files directly. For example, copy layouts/_default/about.html from the theme to your project's layouts folder and modify it there.
