Reduce height of Footer

Hello,

I am using Theme Twenty Seventeen. At the bottom of a page, in the footer area, I want to have Find Us (the address) and my horizontal footer menu in a row, meaning side by side rather than on top of each other floating left.

I also want to reduce the height of the footer. Since I have put a background color on the footer, the footer section is too big. How do I reduce the height on the footer? What is the css?

It seems to me when I add the Text widget and then the navigation widget in the footer, the content displays one on top of the the other and I can’t figure out how to have them displays side by side. How can I fix this?

Thank you!
