#### Custom CSS theme
Quartz supports custom theme for Giscus. To use a custom CSS theme, place the `.css` file inside the `quartz/static` folder and set the configuration values.
For example, if you have a light theme `light-theme.css`, a dark theme `dark-theme.css`, and your Quartz site is hosted at `https://example.com/`:
```ts
afterBody: [
Component.Comments({
provider: 'giscus',
options: {
// Other options
themeUrl: "https://example.com/static/giscus", // corresponds to quartz/static/giscus/
lightTheme: "light-theme", // corresponds to light-theme.css in quartz/static/giscus/
darkTheme: "dark-theme", // corresponds to dark-theme.css quartz/static/giscus/
}
}),
],
```
