Hey Moritz,
first of all, thank you for the purchase!
Social icons (or other widgets) have not been envisaged in the theme’s footer, so there’s no « out-of-the-box » option for that. Technically, it is possible indeed, but will require certain code customization. There are several ways you could proceed:
– add the html markup (i.e. images and links) for the social icons into the « Copyright text » field on the « Page elements » tab of the Theme Options panel, wrapping them into a container (e.g. a div) with « float: left » property or « text-align: left ».
– add the icons into the footer widget area in the « Appearance -> Widgets » admin section, using the Social Media Widgets, and removing the extra margins in the footer widget area by adding this code to the theme’s « style.css » file (opens by default when you visit the « Appearance -> Editor » admin menu):
#footer .widget-footer { margin: 0 !important; }
Sincerely,
Andrii / Satori Studio
