Using Custom Elements Today
summary
Claims that Custom Elements are practical today, backed by a tiny shim and examples: a 4k polyfill that targets IE9+; a drop-down implemented as a semantic-dropdown element that auto-initializes and emits DOM events; a GitHub-backed time element that updates and localizes relative timestamps. Implementation uses document.registerElement/webcomponents.js polyfills, reuses jQuery plugins under attached/detached callbacks, and demonstrates working, usable components rather than vague promises.
