# 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"
```
---
### Use a custom theme (advanced)
To use Hugo pipes to build a custom Reveal.js theme, place the source file (SCSS / PostCSS) in the `assets` directory and set the `custom_theme_compile` param.
```toml
[params.reveal_hugo]
custom_theme = "reveal-hugo/themes/custom-theme.scss"
custom_theme_compile = true
```
<small>
💡 See the [custom theme example presentation](/custom-theme-example/) for more details.
</small>
---
## Bundled themes
reveal-hugo comes with 2 extra Reveal.js themes:
- [robot-lung](https://github.com/dzello/revealjs-themes#robot-lung) (this one)
- [sunblind](https://github.com/dzello/revealjs-themes#sunblind)
<br>
<small>
They live in the `static/reveal-hugo/themes` folder and also [on Github](https://github.com/dzello/revealjs-themes).
</small>
---
## Reveal.js params
Set **snakecase** versions of Reveal.js params, which will be camelized and passed to `Reveal.initialize`.
```toml
[params.reveal_hugo]
history = true
slide_number = true
transition = 'zoom'
transition_speed = 'fast'
```
[Full list of params](https://github.com/hakimel/reveal.js/#configuration)
---
## 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]
highlight_theme = "zenburn"
```
---
## 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.
</small>
---
Here is where to put partials for different presentations and places in the DOM.
<br><br>
| Presentation | Before &lt;/head&gt; | Before &lt;/body&gt; |
|--------------|---------------------------------|---------------------------------|
| All | reveal-hugo/head.html | reveal-hugo/body.html |
| Root | home/reveal-hugo/head.html | home/reveal-hugo/body.html |
| Section | {section}/reveal-hugo/head.html | {section}/reveal-hugo/body.html |
&nbsp;
<small>
💡 You can also create an `end.html` to put content before the end of the `.reveal` div tag.
</small>
---
## Custom CSS Example
In `home/reveal-hugo/head.html`:
```html
<style>
.reveal section h1 {
color: blue;
}
</style>
```
---
## Custom JS Example
In `home/reveal-hugo/body.html`:
```html
<script type="text/javascript">
Reveal.addEventListener('slidechanged', function(event) {
console.log("🎞️ Slide is now " + event.indexh);
});
</script>
```
---
### Extending the layout
#### (alternative)
You can declare a custom CSS or javascript in your configuration.
```toml
[reveal_hugo]
custom_css = "css/custom.css"
custom_js = "js/custom.js"
```
<small>
These files can be located in `static/css`, `static/js` folder
💡 See the [extending layout example](/extending-layout-example/#) for more details.
