Share buttons text label modify. How?

Hello,

somehow I managed myself to make the sharing label stay above the sharing buttons, centering text and buttons to the page.

SEE SAMPLE: http://www.inforc.net

But I would like to have more options to modify that text look, like size, color…

How can this be done? What file do I have to edit?

Thanks.
