Type Alias: FontMark

FontMark = object

Defined in: rcml/src/email/content/json-validator/types.ts:11

A font mark that applies typographic styling to a text node. All attributes are optional — only include the attrs you want to set. null is treated identically to omission: the serializer filters it out and the attribute is not emitted. (The RFM-to-JSON converter always emits all eight keys, setting unset ones to null; sparse editor-produced marks simply omit them instead.) At least one attribute must be present (a bare font mark with no attrs has no effect).
