Calendar is an ancient and not-well-maintained module which may even 
predate html.  (There have even been suggestions that it be dropped.) I 
would not be surprised if the 'css' parameter of formatyearpage were an 
incomplete addition to the first version of HTMLCalendar.  Feel free to 
submit a patch to make the html work better with css, as long as css is 
not made mandatory rather than optional.  (Or should there be two html 
classes? I do not know html well enough to know.)
