To change the style information for the bylines, modify the style element Byline. To change the width, the spacing, or the line around the borders of the byline, modify the style element BylineContainer.

   proc template;
     define style styles.test;
       parent=styles.default;
       style byline from byline /
             background=red
             font_size=2
             foreground=green;
     end;
   run;

   ods html file='temp.html' style=styles.test;
   proc sort data=sashelp.class;
     by sex;
   run;
                                                                
   proc print data=sashelp.class;
     by sex;
