1) A warning is not an error
2) Yes, background colour and foreground colour should be both defined
and have enough contrast, however, adding background:transparent; just
to please a validator is making the validator more important than your
visitors or other developers who have to maintain your work. As
background _does_ get inherited it is not always necessary to define
it, pending the next parent element does have a background defined.
3) It is a validator, a stupid script running on a computer 
4) Pixies do this over night. Or maybe the validator has been changed.
