FontFaceSet

Available in workers

The FontFaceSet interface of the CSS Font Loading API manages the loading of font-faces and querying of their download status.

A FontFaceSet instance is a Set-like object that can hold an ordered set of FontFace objects.

This property is available as fonts, or self.fonts in web workers.

Instance properties

• status Read only
  • : Indicates the font-face’s loading status. It will be one of 'loading' or 'loaded'.
• ready Read only
  • : Promise which resolves once font loading and layout operations have completed.
• size Read only
  • : Returns the number of values in the FontFaceSet.

Events

• loading
  • : Fires when a font-face set has started loading.
• loadingdone
