Background emage behind header on mobile

Hello! Is there a way to make the background image on a page show behind the header on mobile, like it does on desktop? 

As it is now, the mobile header is white (even though I've set it to transparent).

See the home page at christinacrump.com for reference - I would like to see the bubble image behind the header on mobile, like it shows on desktop.

(it's still a work in progress!)

You can use this to Website Tools > Custom CSS

@media screen and (max-width:640px) {
.Mobile-bar.Mobile-bar--top {
    background-color: transparent;
}
body#collection-627f008f357b99450205d805 {
    margin-top: 0px !important;
}
}
