# Configuration

## Reveal.js themes
Put in `config.toml` or a presentation's front matter.
Use the `theme` key for themes that come with Reveal.js.
```toml
[params.reveal_hugo]
theme = "moon"
highlight_theme = "zenburn"
```

## Extending the layout
Use partials to add HTML to the page at the closing of the head and the body tags, either for all presentations or just a specific one.
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.
<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 |
---
## Example customization
In `home/reveal-hugo/head.html`:
```html
<style>
.reveal section h1 {
color: blue;
}
</style>
```
In `home/reveal-hugo/body.html`:
```html
<script type="text/javascript">
Reveal.addEventListener('slidechanged', function(event) {
console.log("🎞️ Slide is now " + event.indexh);
});
</script>
```
