I would like to remove the black border line from around the "X bloggers liked this." box at the bottom of the content portion of each of my posts. A good example page would be: http://exploratorius.us/2013/08/06/waking-with-the-ospreys/
The black -- to me, at least -- looks busy, and I'd like to remove it, but keep the gray shadow that's on the outside of it. Is that possible?
Thank you for any assistance you can provide.
The blog I need help with is exploratorius.us.
