In this iteration, these buttons only use unicode symbols. You could also use text or icon fonts. Please see my Dribbble shot or [email protected] for more examples. The next step would be to make them as cross-browser compatible as possible. If you have questions, feel free to ask on Twitter: @saschamt. Kind regards, Sascha Michael Trinkaus.
A repost of a bunch of CSS buttons I found on GitHub, made by @skidding. Planning to contribute on developing this project further. It would mean a lot if you guys could check these out and give suggestions on what can be improved. Any feedback is useful. Thanks!
