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

Disallow missing generic families in lists of font family names.

```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.
