Allow, but not necessarily recommend or advocate. Closing tags gives the 
processor more explicit instructions on how to deal with ambiguities, 
and let's the code be checked for good form. I close all my tags as a 
matter of principle. Unless there is some harm in doing so - I think it 
is a good practice.

The combined open close tags such as <hr/> should be used with a space 
before the / to make sure it works on old and new browsers.

Try: <hr />

Again, it's just a good practice.
