Help needed, The boarder isn't big enough around the comments section

Hi Thank you for this great plug in, It’s just what I need, it’s working fine but it messes up a little, Please look at this page and scroll to the bottom and you will see what I mean.

Is there anyway to make the border bigger so it doesn’t spoil the layout?

Thank you for the great plug in
