Hey Again,

You only seem to have the 2 Column Footer Option active: 

Click To Open Larger Image.

Please enable the 3 Column Option so we can write up custom css for the specific column widths.

Thanks 

Hey Again,

Add this into the Custom CSS box in your Salient Theme Options panel (We write all Custom CSS in the Live Browser to ensure accuracy. If you cannot see any changes, make sure there is no red cross in the Custom CSS Box as any syntax error would cause all CSS under that line of code to not show up on the Frontend):

#footer-outer .col.span_4:first-child {
    width: 49% !important;
}
#footer-outer .col.span_4 {
    width: 23.5% !important;
}

Thanks

Hey Again,

Use the Below Revised CSS

/* below css would work on screen size larger than 1000px */
@media only screen and (min-width: 1000px) {
    #footer-outer .col.span_4:first-child {
        width: 49% !important;
    }
    #footer-outer .col.span_4 {
        width: 23.5% !important;
    }
}

Thanks
