Space between the like buttons and next Article title

Hello,
you greatly helped me in the past to fix the space between jfbc comment and next article, by using the .jfbc css code with bottom margin.
For some reasons I had to desactivate de "comment" part of JFBC connect, leaving only the "like, + tweet" bar. But then, as soon as I desactivate comment it, space between the plugin and the next title is forgotten.

What code line should I add to css to put some space between the like line and the next article title ? Here's a screenshot.

Thank you very much.
