+++ title = "Syntax Highlighting" weight = 80 +++

Zola comes with built-in syntax highlighting but you first need to enable it in the configuration.

Once this is done, Zola will automatically highlight all code blocks in your content. A code block in Markdown looks like the following:

```rust
let highlight = true;
```

You can replace the rust by the language you want to highlight or not put anything to get it interpreted as plain text.

Here is a full list of the supported languages and the short names you can use:

If you want to highlight a language not on that list, please open an issue or a pull request on the Zola repo. Alternatively, the extra_syntaxes config option can be used to add additional syntax files.

If your site source is laid out as follows:

.
├── config.toml
├── content/
│   └── ...
├── static/
│   └── ...
├── syntaxes/
│   ├── Sublime-Language1/
│   │   └── lang1.sublime-syntax
│   └── lang2.sublime-syntax
└── templates/
    └── ...

you would set your extra_syntaxes to ["syntaxes", "syntaxes/Sublime-Language1"] in order to load lang1.sublime-syntax and lang2.sublime-syntax.
