# Configuration
|
|
|
|
Place configuration values in `config.toml` or a presentation's front matter (`_index.md`).

## Reveal.js themes
|
|
|
|
Themes control the look and feel of your presentation. Set the `theme` param to any [valid Reveal.js theme](https://github.com/hakimel/reveal.js/#theming).
|
|
|
|
```toml
|
|
[params.reveal_hugo]
|
|
theme = "moon"
|
|
```
|

|
## Use a custom theme
|
|
|
|
To use a custom Reveal.js theme, place the CSS file in the `static` directory and set the `custom_theme` param.
|
|
|
|
```toml
|
|
[params.reveal_hugo]
|
|
custom_theme = "reveal-hugo/themes/robot-lung.css"
|
|
```
|

## Reveal.js params
|
|
|

|
|
|
|
```toml
|
|
[params.reveal_hugo]
|
|
history = true
|
|
slide_number = true
|

## highlight.js themes
|
|
|
|
To change the syntax highlighting theme, set the `highlight_theme`
|
|
to a valid [highlight.js theme name](https://highlightjs.org/static/demo/).
|
|
|
|
```toml
|
|
[params.reveal_hugo]

```

## Extending the layout
|
|
|
|
Use partials to add HTML to the page for one or all presentations at a time.
|
|
|
|
<small>
|
|
💡 This is the recommended way to add script and style tags to customize your presentations.
|
|

|
|
|
|

|
|
|
|
Here is where partials go for different presentations and places on the page.
|
|
