    Instantiating elements

    The common techniques of creating elements still apply to custom elements. As with any standard element, they can be declared in HTML or created in DOM using JavaScript. Instantiating custom tags

    Declare them:

    <x-foo></x-foo>

    Create DOM in JS:

    var xFoo = document.createElement('x-foo');
xFoo.addEventListener('click', function(e) {
    alert('Thanks!');
});

    Use the new operator:

    var xFoo = new XFoo();
document.body.appendChild(xFoo);
