Unknown pseudo-element or pseudo-class :first-child

7  	  	 Unknown pseudo-element or pseudo-class :first-child
9 		Unknown pseudo-element or pseudo-class :first-child
12 		Unknown pseudo-element or pseudo-class :first-child
15 		Unknown pseudo-element or pseudo-class :hover

This seems odd to me...I get this error using the File Upload css validator
