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]
    style = "base16-snazzy" # choose a color theme or create your own
    guessSyntax = false     # if set to true, avoid unstyled code if no language was given but mermaid code fences will not work anymore
