Salve a tutti!
ho provato a fare il validator del mio css ma mi da (tra l'altro) questi errori :

codice:
Line: 6 Context : body 
Property scrollbar-track-color doesn't exist : #cdd5dd 

Line: 7 Context : body 
Property scrollbar-face-color doesn't exist : #d7dde3 

Line: 8 Context : body 
Property scrollbar-highlight-color doesn't exist : #ffffff 

Line: 9 Context : body 
Property scrollbar-3dlight-color doesn't exist : #cdd5dd 

Line: 10 Context : body 
Property scrollbar-darkshadow-color doesn't exist : #cdd5dd 

Line: 11 Context : body 
Property scrollbar-shadow-color doesn't exist : #ffffff 

Line: 12 Context : body 
Property scrollbar-arrow-color doesn't exist : #ffffff 

Line: 22 Context : table 
Property border-spacing-bottom doesn't exist : 0

Dove sto sbagliando?
