[CSS] about compound attributes.

Consider task of defining animation[1] of background-position[2] 
attribute values.

As an example: the desire is to be able to animate vertical and 
horizontal positions of the background image using different timing 

Similar requirement is for accessing such compound values from scripting.

I think it would be nice if each shortcut attribute like 
background-position above will have also scalar counterparts like
'border-width' (shortcut) and 'border-width-top' (corresponding scalar 

If it is too much then how to deal with compound attributes in animation 
and the like cases?
