oUF Phanx Layout - Fading Out of Combat?

[Faerydae]

I adore the Phanxs oUF layout, it's both minimalist and stylish.
The only thing that could perfect it for me personally, is if I could have my player and pet bar fade out completely when out of combat.
I like as little as possible visible on my screen when I'm toodling around.
Could anyone tell me if this is possible, and if so how to implement it?
Please bear in mind that I'm a complete simpleton when it comes to understanding code.

Thank you,
