This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for the proper prefixes to use in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the spec changes.

The load() method of the FontFaceSet forces all the fonts given in parameters to be loaded.


result = aFontFaceSet.load(font);

result = aFontFaceSet.load(font, text);


A Promise of an Array of FontFace loaded. The promise is fulfilled when all the fonts are loaded; it is rejected if one of the fonts failed to load.



// returns a promise that will be fulfilled or rejected according the success to load MyFont
// The code in 'then' can assume the availability of that font.

document.fonts.load("12px MyFont", "ß").then(…);
