Trying to expand footer

I am trying to get my footer to expand the width of the page. I understand this is not a built-in option in Minsk. Any suggestions? Here is what I have in the main settings injection code area, but it is restricted and not expanding:

<style type="text/css"> #footer{ position: bottom; width: 100% !important top:0; right:0; bottom:0; left:0; background-color: black; text-align:left; font-size:14px; font-family:open sans; margin:0 auto; color:#ee771b; }
