Function: getFallbackFontFamily()

getFallbackFontFamily(fontFamily): string

Defined in: rcml/src/email/theme-defaults.ts:154

Return the CSS generic-family fallback for a main family name. The lookup is keyed by DefaultFontFamily enum keys — e.g. 'TimesNewRoman', 'CourierNew'. Anything the map does not know about falls back to the Helvetica default ('sans-serif'), so the function never returns undefined and never throws.

Parameters ​

fontFamily ​

string

A DefaultFontFamily key, or any other string (unknown strings get the Helvetica fallback).

Returns ​

string

A CSS generic family: 'sans-serif', 'serif', 'monospace', or 'cursive'.
