turning off mobile responsiveness

Hi!
Thanks for the great theme. I’m using Legacy on this site – http://lovelotscakes.com. The site owner didn’t want it to be mobile responsive, so I removed the mobile responsive section of the css and added specific widths to the different wrap elements. However, when viewed on tablets and mobile phones, the backgrounds (for the slider, menubar, and footer) do not extend all the way to the edge of the page, and the footer widgets are also cut off. Can you point out how I can fix this? Thanks!
