By including the LivePhotosKit JS script on your page, you can create players by simply adding declarative markup to your HTML. As the page loads, LivePhotosKit JS will determine what player instances are on the page and initialize them. You can use any HTML tag that supports child nodes.
At minimum, each tag requires the following data attribute: data-live-photo. Doing this allows LivePhotosKit JS to find the DOM elements to be initialized as players.
I’ve come around to really liking Live Photos, but I don’t think I’ll be enabling them for the photos I share here. Most of my photos for the site aren’t shot with an iPhone, anyways.
