The Relearn theme uses [Hugo's built-in syntax highlighting](https://gohugo.io/content-management/syntax-highlighting/) for code.
## Markdown syntax
Wrap the code block with three backticks and the name of the language. Highlight will try to auto detect the language if one is not provided.

# if set to `guessSyntax = true`, there will be no unstyled code even if no language
# was given BUT mermaid code fences will not work anymore! So this is a mandatory
