The attached sample code creates an output window with border box/text box with background colors. When the output is saved as interactive HTML background colors and font type (bold, size) aren't showing. See attached image.
Many thanks
lu = lineup box(n col(2), spacing( 25 ));
vlb = V List Box(
Text box("LINE1"),
Text box("LINE2"),
Text box("LINE3")
);
bb = Border Box(Sides(30), Left( 20 ), Right( 20 ), Top( 20 ), Bottom( 20 ), << Set Background Color("RED"), vlb);
lu << append(bb);
bb = Border Box(Sides(30), Left( 20 ), Right( 20 ), Top( 20 ), Bottom( 20 ), << Set Background Color("GREEN"), vlb);
lu << append(bb);
bb = Border Box(Sides(30), Left( 20 ), Right( 20 ), Top( 20 ), Bottom( 20 ), << Set Background Color("YELLOW"), vlb);
