## Note on Syntax Highlighting

The theme supports syntax highlighting.
By default, it uses a slightly modified version of the `algol` theme, defined in `assets/css/syntax-highlighting.css`.
The code block background can be changed with the `--code-background-light` and `--code-background-dark` variables in [`custom.css`]({{% relref "advanced-customization.md#custom-css" %}}) or in a [custom color file](#adding-a-custom-color-palette).
To use a custom color scheme, you can overwrite this file.
Other color schemes, e.g. Monokai, can be applied using [inline styles]:
The theme supports syntax highlighting, and you can specify the theme as follows:

```toml
[markup]
[markup.highlight]
noClasses = true
style = 'monokai'
style = 'algol'
```

Alternatively, you can generate a stylesheet for your preferred color scheme with this command:
`algol` is the recommended theme, and for it to work, the background-color of the code
elements is enforced.
This has the side effect of breaking other color schemes, e.g. Monokai.

```shell
hugo gen chromastyles --style monokai > assets/css/syntax-highlighting.css
```
You can make them work by removing `!important` from the background color of the code pre elements.

I suggest trying [color schemes](https://xyproto.github.io/splash/docs/all.html) and see what can work for you.
