Aegaeus Full-Width Boxes

Hello,

I am using fullwidth boxes in the Aegaeus theme. On the Mac PC and iPad there is a light grey line that separates the boxes. I used six with box size=”one-third” and the line separates the three boxes side-by-side for the first three and the three right under it.

The problem is on the iPhone, the light grey line does not show around the entire box – it only shows partially around some boxes, but not all boxes. This does not look nice.

I would prefer that the box not show at all on the mobile phone device. Is there a custom CSS code that I can enter that would eliminate the box lines on a mobile phone device? If need be, I am also open to adding a code that would eliminate the grey line on all computer and mobile devices.

I can send you my URL if it helps to see what I am referring to.

Thank you,
Rick
