<!-- Answer -->
To load custom fonts locally in Superset 6.0.0, you'll need to mount your font files and inject them via CSS. Here's how:
**1. Mount your fonts directory in `docker-compose.yml`:**
```yaml
volumes:
- ./fonts:/app/superset/static/assets/fonts
- ./custom-fonts.css:/app/superset/static/assets/custom-fonts.css
- ./spa.html:/app/superset/templates/superset/spa.html
- ./superset_config.py:/app/pythonpath/superset_config.py
```
**2. Create `custom-fonts.css` with `@font-face` rules:**
```css
@font-face {
font-family: 'MyCustomFont';
src: url('/static/assets/fonts/MyFont-Regular.woff2') format('woff2');
font-weight: 400;
font-style: normal;
}
```
Include weights 200, 400, 500, 600 for full UI coverage.
**3. Create `spa.html` to inject the CSS globally:**
```html
{% extends "superset/spa_base.html" %}
{% block head_extra %}
{{ super() }}
<link rel="stylesheet" href="/static/assets/custom-fonts.css">
{% endblock %}
```
**4. Configure the theme in `superset_config.py`:**
```python
THEME = {
"token": {
"fontFamily": "MyCustomFont, -apple-system, BlinkMacSystemFont, sans-serif"
}
}
```
The key is that the [`THEME` token only sets the CSS `font-family` property—it doesn't load the font itself](https://github.com/apache/superset/discussions/34397#discussioncomment-13939721), so you need both the `@font-face` rules and the template injection.
Note: Superset 6.0.0 has a [known issue where the default Inter font fails to load](https://github.com/apache/superset/issues/37226), so using custom local fonts actually bypasses this problem.
