Mobile Display Option

Hello,

I wanted to shift the notification message up a little from the bottom of the screen. I wanted to do this because it blocks the sticky add-to-cart on mobile devices and coupon box on desktops. I used the following CSS which worked great for desktops but not for mobile/tablets.

body #message-purchased {
bottom: 85px;
}

Further, how could I disable the notification to appear on top of the slide-out cart? It blocks the view cart/checkout button.

Thanks.
