In particular, since inherit and initial can't be used within a shorthand, Gecko follows the rule that if some subproperties of a shorthand are inherit or initial, then in order for the shorthand to serialize as other than "", all must be. This vastly simplifies serialization code (and, if we ever specify it, specification). -David -- π L. David Baron http://dbaron.org/ π π’ Mozilla Corporation http://www.mozilla.com/ π
