i want a 1px solid line above each title
but in the case of 2 posts at the same date, i don't want 2 lines for the 2 posts.
i just want the line above the first post.

how to add that line ?
where in the index.php ? in the style.css ?

thank you if you can help!

The quickest thing I can think of is putting <hr /> at the top of the LOOP field in ATO>Style & edit Center Column.
