## Options

### family

The `family: string | string[]` option defines the fallback families used to polyfill `fangsong`.
It accepts an array or a comma-separated string.

```js
import postcssFontFangsong from "postcss-font-family-fangsong";

postcssFontFangsong({
  family: "fangsong, FangSong, FZFangSong-Z02, FandolFang",
});
```

### preserve

The `preserve: boolean` option controls whether `fangsong` should be preserved in the transformed CSS output.
Its default value is `true`

```js
postcssFontFangsong({
  preserve: true, // preserve `fangsong` in the transpiled output
});
```

When both `family` and `preserve` are specified, `preserve` is a no-op.
