/* ===== tabbox.css =====================================================
  == Styles used by the XUL tabbox element
   
    The default style of these tabs is that of an NSTabView with tabs at
    the top in the "regular" size. These tabs can be used with or without
    a tabbox element.
    For bottom tabs you should use the "tabs-bottom" class on the tabbox
    or the tabs element. Bottom tabs use a style that's similar to the
    one used in Adium.
