Center the Footer for Media Query CSS for Weta

Hi there,

I am trying to center our footer so that it aligns with our site info + social media for the mobile view (@ media screen and (max-width: 768px) , but when I try text-align: center, it doesn’t align with the bottom. Also text-align: center does not work for the images that I have used in a text-widget. Could you advise? Link to website is http://www.ottiya.com
