Footer: aligning margins to header and reducing height

Site URL: https://www.deakin.group/

Hello

I would like to reduce the overall footer height and align the outer elements of the text (margin) to be the same as the header. I have taken a snapshot showing header and footer against each other.

1. Can I add more parts to the grid to accomplish this?
2. Or, is there code I can use to change the margin of the footer to match the header?
3. How can I change the overall height of the footer. (redline on image is approx height of footer)

Thanks, Chris
