Footer doesn't scale to larger screens, looking for custom CSS.

Password: marley

Hello,

I am looking for some help regarding the width of my footer on larger screens.

As it stands if i load my website on a larger screen (attached images are loaded on a 21.5 inch imac) my footer wont
scale to fit the width of my header.

Just looking for help regarding what custom CSS i could use to fix this?

Any help would be great,
Thank you.
