It is on the landing page. Roughly halfway down.
That said, that hero example would be impossible to show in anything other than plain HTML as you would need a react version, an Angular Version and a Vue version. It is a demo of what it can do rather than than how.
Funny how that's not how it's advertised on the landing page. The first animation of its use is just basically plaintext HTML document.
I can't imagine using it for that.
