can't get 'make-the-whole-body-a-dropzone' example to work

[parmentelat]

Duplicating issue #1998 after realizing that issues were not the right channel to use

---

at the bottom of this page
https://github.com/dropzone/dropzone/wiki/make-the-whole-body-a-dropzone

is a link to a live demo but that link is broken and leads to a 404
http://www.dropzonejs.com/demos/full-page-dropzone.html

so I tried to mimick that behaviour but it looks like something is not quite right in that example

making the link live again would greatly help out I guess

thanks !
