.htaccess 403 redirects not working

.htaccess 403 redirects not working

I have this code in my .htaccess file:
Options All -Indexes
order deny,allow
deny from all
ErrorDocument 403 /www/landing.html
<Files landing.html>
allow from all
</Files>
<Files styles.css>
allow from all
</Files>
<Files prefixfree.min.js>
allow from all
</Files>
which is located on my server at /www. There is an index.html,
loading.html, and a .htaccess in this folder, then the css and js files
are in their respective subfolders. The site is hosted on Hostgator.
When I load up my site, I get this error:
Forbidden
You don't have permission to access / on this server.
Additionally, a 403 Forbidden error was encountered while trying to use an
ErrorDocument to handle the request.
So it's not finding the document. If I change my code to ErrorDocument 403
/loading.html then my site goes down entirely and the loading icon just
spins without loading anything. downforeveryoneorjustme.com also reports
that it is down. Is there something I'm doing wrong?
