Thread:Extension talk:MobileFrontend/change Background on Mobile View Only

Hello, I am having some issues with our private wiki with our custom background. On the desktop site i have a really dark background that is fine because the pages themselves are white. On the mobile view however, everything is transparent and the background shows through, causing everything to become unreadable. I can work around this by enabling the experimental mode on the mobile version, however i do not want to have each user do this on every mobile device. Can someone point me in the direction I need to set a static background on the mobile view or exclude the background on it somehow?
