So to sum what I'm reading, it's a neat little demonstration of the :target pseudoclass.

But:

- No, the entire website isn't a single HTML file (it's also images and a CSS file)

- So no, you can't download a single file and have it work offline

- And no, this won't work well with screenreaders and other non-standard clients

- And no, this doesn't scale well to larger sites

- And no, this won't be indexed well by search engines

- And no, you don't need this to avoid Javascript navigation (just use multiple HTML files)
