Hello!!

I already managed to alter the social media icons in the header with a former ticket here. 

/*add new social icon main*/

#header-outer #social-in-menu .fa-flickr:before,#header-outer #social-in-menu .fa-flickr:after, .material #slide-out-widget-area.slide-out-from-right .fa-flickr:after {
    content: "f270" !important;
}

#header-outer #social-in-menu .fa-github-alt:before,#header-outer #social-in-menu .fa-github-alt:after, .material #slide-out-widget-area.slide-out-from-right .fa-github-alt:after {
    content: "e077" !important;
}

Can't figure out how to alter the icons in the footer.

Looking for to get a hint.

All the best,
Peter

Works like a charm!!

Thank you very much!!

Best,
Peter
