As [reported by @LauLauThom](https://forum.image.sc/t/53641/3): For the page https://imagej.net/scripting/parameters: ## GitHub preview  ## Live site  Questions to investigate: * Which syntax highlighting technology and color theme is used on the live site for code fenced code blocks? ([Hint](https://github.com/imagej/imagej.github.io/blob/feef5a71dc2de0225bfdca7171a05f3e31b92575/assets/css/main.css#L3). What if we use fruity instead?) * What does GitHub use in the Preview pane, and is there any way to use that with Jekyll as well?
