Specify the events. The following events are from the SAS tagset TAGSETS.HTMLCSS, and they show how ODS creates notes. By defining the Gnote event and setting the proper style in the right place, ODS creates a two-cell table that has a banner using the appropriate banner style and a content cell that has the appropriate content style.

define event Gnote;
           start:
               put '<div>';
               trigger align;
               put '>';
               put '<table>';
               put '<tr>' nl;
           finish:
               put '</tr>' nl;
               put '</table>' nl;
               put '</div>';
       end;

       define event GBanner;
           put '' nl;
           trigger pre_post;
           put '' nl;
       end;

       define event GNContent;
           put '';
           trigger pre_post start;
           put VALUE;
           trigger pre_post finish;
           put '';
       end;

       define event noteBanner;
           style=NoteBanner;
           trigger GBanner;
       end;

       define event NoteContent;
           style=NoteContent;
           trigger GNContent;
       end;

       define event note;
           trigger Gnote start;
           trigger noteBanner;
           trigger noteContent;
           trigger Gnote finish;
       end;

       define event WarnBanner;
           style=WarnBanner;
           trigger GBanner;
       end;

       define event WarnContent;
           style=WarnContent;
           trigger GNContent;
       end;

       define event Warning;
           trigger Gnote start;
           trigger WarnBanner;
           trigger WarnContent;
           trigger Gnote finish;
       end;
