Hello, in the byline can you change the color, I might be in the wrong area but I want to put a blue bar between the header and the body, is this possible, Regards, Mick.

It seems like you would use a %bar1 or %bar2 and style it as you want.

where would I put that, Mick

I put %bar2 in the byline box, but nothing happened

When you said you wanted a line between the header and the body I thought you meant the site header. It sounds like you want a bar between each post/page title and the body of the post/page. If that is the case then you would go to ATO>Style Posts & Pages and put a bottom border in the Headline box or a top or bottom border in the Byline box.
