Function toCSSFontFamily

toCSSFontFamily(family: string, fallbacks?: readonly string[] | null): string
The CSS font-family value that paints family: the family, then the fonts that stand in for it where it is not installed, then fallbacks, each followed by its own stand-ins.

A stand-in is the family family is measured by and that family's open metric-compatible twins, so text painted on a machine without the original still fits its measurement.
Parameters
- family: string
  The family as a style names it.
- Optionalfallbacks: readonly string[] | null
  Families or CSS generic names to try after it.
Returns string

IFont.toCSSFontFamily('Calibri', ['sans-serif']); // 'Calibri, Carlito, sans-serif'
IFont.toCSSFontFamily('Aptos Narrow', ['sans-serif']); // '"Aptos Narrow", "Intos Narrow", Calibri, Carlito, sans-serif'
```
