CSS Font Loading API - Web APIs 编辑

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The CSS Font Loading API provides events and interfaces for dynamically loading font resources.

Note: This feature is available in Web Workers (self.fonts provides access to FontFaceSet).

Interfaces

FontFace: Represents a single usable font face.
FontFaceSet: An interface loading font faces and checking their download statuses.
FontFaceSource: A mixin providing all of the fonts used in font-related operations, unless defined otherwise. It defines the FontFaceSources.fonts property available to Document and WorkerGlobalScope.
FontFaceSetLoadEvent: Fired whenever a FontFaceSet loads.
