Hello,

Sorry for the late reply.
Do you mean center widgets in mobile? It doesn’t seem to need to center them in desktop as they are the first of three columns.
To center in mobile please add this code into your custom css box:

@media (max-width: 480px){
footer .footer_social_icons {
    width: 46% !important;
    margin-left: 84px !important;
}
footer #text-6 {
    padding-left: 78px !important;
}}

Result screenshot.
Let us know.

Best regards!
