If you're testing this from within your network, it might actually be
working, and you're just seeing a side effect of internal connections
staying internal (you don't go out, come back in again, and get
redirected by your router), even if you're trying to browse to your
public IP address (you're just going in and around the internal side of
your modem/router).

Try this test:  Go to a website service like the HTML validator at the
W3C, and try and validate your webpage.  Also tick the option to show
your source.  If you see your website source code come back in the
results, regardless of any errors or correctness to the HTML, your web
server is accessible from the outside world.

I'll leave the secondary issue of good or bad HTML to your own
judgement.  Though, remember, broken code seems to work for some people,
but then doesn't for others.

If you're leaving a server open to the outside world, check you're not
exposing any security vulnerabilities in the server; and through it,
your system.  Also, check you don't leak out private information, use
the methods provided by Apache to limit access to things (by address, by
logon credentials, etc.).
