Socializr

Socializr is a social sharing stack, that allows visitors to share your website to the major different social sharing services. Socializr changes the way people share sites, it doesn't just pin some buttons on your website that don't even match your site's style and theme. But instead, it triggers a lightbox with over half a dozen sharing options. IT takes what was once ugly and makes it stylish. It's also responsive. And if you don't want a floating button, you can use your own trigger! :)
