My summary-links webpart in Office 365 is having difficulty placing the groups in columns. There seems to be a wide fixed margin. I'm willing to correct it using CSS, but I can't find the offending style.

Its not margin
you are having an issue with. Looks like its width
from your screen shot. You have given width:25%
and the div
tags are by default display:block
- Try making them display:inline-block
.
