Jekyll theme for research project websites 🧫

petridish 🧫

Petridish is a Jekyll theme for research project websites. Or your personal blog or lab website. 👩‍🔬 It's mobile-friendly (thanks to Bootstrap 5), free, easy to customize, and designed to work well with GitHub Pages.


See the demo website for instructions:

The instructions below can be adapted/included in the README of your site repository.


This website makes use of the static website generator Jekyll and the Petridish theme. Each commit to main will automatically trigger a new build on GitHub Pages. There is no need to build the site locally, but you can by installing Jekyll and running bundle exec jekyll serve.

Minor changes can be committed directly to main.

Changes requiring review (e.g. new blog posts) should be created in a separate branch and submitted as a pull request. Some guidelines:

  • Use 72dpi as image resolution
  • Place background images in assets/backgrounds/, name them after their corresponding page/post and ideally crop them to 2100 x 700px
  • Place content images in assets/images/, name them after their corresponding page/post + a suffix, e.g. -figure-1
  • Add tags to posts to create relevant groups (e.g. same topic, project).
  • Create internal links as [previous post]({{ '/permalink/to/post/' | relative_url }})

Repo structure

The repository structure follows that of Jekyll websites.
