Template used FontAwesome&IcoFont icon packs . You can place icons just about anywhere using a CSS style prefix and the icon’s name. Font Awesome and IcoFont is designed to be used with inline elements (we like the i tag for brevity, but using a span is more semantically correct).
Font Awesome and IcoFont icons automatically inherit CSS size and color. This means they blend in with text inline wherever you put them.
