Remove the border to allow a more refined and clear appearance.
Since the only usefulness of the border is for white and very light colours over the white page background, add a subtle shadow.
The aim is to remove anything that can be perceived as 'negative' without a reason for it to exist (Its absence doesn't hurt but its presence doesn't help).
