Stackicons are icon fonts for the web, designed to do more — with multiple button shapes and a unique “multi-color” option. The Stackicons-Social font and Sass-based construction kit are free and open source, created by Parker Bennett.

Stackicons-Social includes over 60 up-to-date icons for modern social brands — from App.net to Zerply. Each icon was meticulously crafted to look great at multiple sizes, with five different button shapes, from square to circle, or icon-only.
