Hey guys this is Joshua, and Apple just released iOS 10 a few weeks ago, and one of the more exciting things included was a 3D Touch API for web developers. 3D Touch we know, it's a gimmick, but it is a useful input method, for those spurts of inspiration where it fits. And what's cool is you can get further backwards support by using the Safari 9 "Force Touch" API.
I've prepared a little example bubble, for your amusement. Enjoy.
