# font-family-no-missing-generic-family-keyword

Disallow missing generic families in lists of font family names.

<!-- prettier-ignore -->
```css
a { font-family: Arial, sans-serif; }
/**                     ↑
 * An example of generic family name */
```

The generic font family can be:

- placed anywhere in the font family list
- omitted if a keyword related to property inheritance or a system font is used

This rule checks the `font` and `font-family` properties.

## Options

<!-- prettier-ignore -->
```css

```

```

The following patterns are _not_ considered violations:
