i already have the 3 column footer but underneath this i would like a space where i can add a logo of all the companies we are affilliated with.
not sure how to do it? or if it can be done? would need it to be full width if possible.
The best option would be to add the logo’s in a footer widget area. Maybe consider using the WordPress gallery widget; it has a slideshow option which will help save some space yet display all the logos in a slideshow.
