Values for the
k attribute specifying fonts by their general properties.
- Core Media
Some media formats allow the specification of font family names to be used to style text they carry. Sometimes, an external specification such as CSS be used to style the text carried by the media format. In either case, the specification may be concrete, indicating an installed platform font (e.g., "Times New Roman", Helvetica). It may be abstract, indicating a category of font to use (e.g., serif, sans-serif). This abstract designation is often termed a "generic font family".
The Media Accessibility framework can map eight categories of abstract fonts to an installed font. Users may choose to override each of these categories to a different installed font. (See Media Accessibility Function.)
