The FontFace interface represents a single usable font face. It allows control of the source of the font face, being a URL to an external resource, or a buffer; it also allows control of when the font face is loaded and its current status.

Constructor

FontFace()

Constructs and returns a new FontFace object, built from an external resource described by an URL or from an ArrayBuffer.

This interface doesn't inherit any property.

FontFace.display

A CSSOMString that determines how a font face is displayed based on whether and when it is downloaded and ready to use.

FontFace.family

A CSSOMString that retrieves or sets the family of the font. It is equivalent to the font-family descriptor.

FontFace.featureSettings

A CSSOMString that retrieves or sets infrequently used font features that are not available from a font's variant properties. It is equivalent to the font-feature-settings descriptor.
