Fires a custom event on the page as soon as Typekit finishes loading or fails to load. Add this in place of the standard Typekit.load() snippet to enable listening for the event in your own JS (useful for controlling how text appears on page load).

typekit-finish.js

function triggerTypekitFinish() {
  if (typeof window.CustomEvent === 'function') {
    var event = new CustomEvent('typekit-finish');
  } else {
    var event = document.createEvent('CustomEvent');
    event.initCustomEvent('typekit-finish', true, true, {});
  }
  document.documentElement.dispatchEvent(event);
}
try {
  Typekit.load({
    active: triggerTypekitFinish,
    inactive: triggerTypekitFinish
  });
} catch(e) {
  triggerTypekitFinish();
}
