Responsible Web Components
Jeremy Keith has taken Dave Ruperts podcast web component and forked it to become a little more progressively enhanced. There’s more to do, as he points out, like applying an ARIA roles and extending it with <audio> rather than a link. If you fancy a go, Fork it.
…web components—or more specifically, custom elements—already allow us to extend existing HTML elements. That means we can use web components as a form of progressive enhancement, turbo-charging pre-existing elements instead of creating brand new elements from scratch. That way, we can easily provide fallback content for non-supporting browsers.
