ICS Hugo Theme is an open-source, lightweight blog theme for Hugo that merges the design of ivy-hugo-theme and cupper-hugo-theme to produce a simple, responsive static website.
What is ICS Hugo Theme?
ICS Hugo Theme is a Hugo blog theme created by shenweiyan, available on GitHub under the repository name ICS-Hugo-Theme. It takes Markdown content files as input and outputs a static HTML blog with a clean home page and an about page, as demonstrated in the theme's preview screenshots. The theme is built to work with both the Hugo static site generator and Blogdown, the R package that lets you create Hugo sites from RStudio.
Key Features
- Merged from two themes — The theme combines the ivy-hugo-theme and cupper-hugo-theme, bringing together their navigation, typography, and visual styles into one package.
- Lightweight and responsive — The source emphasizes a simple, minimal design, and the layout adapts to mobile and desktop screen sizes.
- Hugo-native — Drop the theme into your Hugo site's themes folder, set the theme name in the config file, and Hugo renders your content automatically.
- Blogdown compatible — The author explicitly documents using it with Hugo and Blogdown, so R users can write posts in R Markdown and publish them as static HTML.
- Live demo available — The maintainer runs two example sites (ics.weiyan.cc and blog.weiyan.cc) that show the default home and about page templates.
- Open source on GitHub — The full source code, including templates, CSS, and configuration files, is publicly available for download, use, and modification.

- R and Blogdown users — Researchers and data scientists who prefer writing in R Markdown and publishing with Blogdown can use this theme because of its documented Blogdown support.
- Theme developers — Developers learning Hugo theme development can read the merged codebase of two existing themes and see exactly how their templates and styles are combined.
