Sprinkle Pro - Social Media Icons Setup
This theme uses the Simple Social Icons Plugin, which can be obtained here or by searching in Dashboard > Plugins > Add New.
In the Widgets menu, drag the widget labeled “Simple Social Icons” into a widgetized area.
The demo displays them in the Primary Sidebar, Custom Instagram Page, and Nav Social Menu widget areas. The icons in Nav Social Menu display as flags, while the other icons display as squares.
Configure the widget by choosing a title, icon size and color, and add the URLs to your social profiles.
