Footer Height

I would like to keep the footer row w/ widgets, but I only need the equivalent of one row height. So – maybe 100px, tops, to show logo and social icons. I cannot figure out how to change the height for the footer container. I can make it not display by changing the #footer id, but I can’t make it a certain height. Can you tell me how to change the CSS for this? I’m using the Highend Child Theme.

thanks –
