The Relearn theme uses Hugo's built-in 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.

```json
[
  {
    "title": "apples",
    "count": [12000, 20000],
    "description": {"text": "...", "sensitive": false}
  },
  {
    "title": "oranges",
    "count": [17500, null],
    "description": {"text": "...", "sensitive": false}
  }
]
```

Renders to:

[
  {
    "title": "apples",
    "count": [12000, 20000],
    "description": {"text": "...", "sensitive": false}
  },
  {
    "title": "oranges",
    "count": [17500, null],
    "description": {"text": "...", "sensitive": false}
  }
]

Supported languages

Hugo comes with a remarkable list of supported languages.

Recommended configuration

You can choose a color theme from the list of supported themes and add it in your config.toml

[markup]
  [markup.highlight]
    # if `guessSyntax = true`, there will be no unstyled code even if no language
    # was given BUT Mermaid and Math codefences will not work anymore! So this is a
    # mandatory setting for your site if you want to use Mermaid or Math codefences
    guessSyntax = false

    # choose a color theme or create your own
    style = "base16-snazzy"
