I made a working Twitter "Tweet" button through: https://about.twitter.com/resources/buttons#tweet (which indeed does appear on my site on localhost) and really need a Facebook "Share" button that matches it in color scheme, font type/color, and highlight effects.
However, the blue button does not seem editable by CSS (just as Twitter's doesn't). Would love some help/direction about how to make these match.
*EDIT - I removed the first part of the question and just left the UX portion for this site. Thanks.
