Hi tuanphan, on the homepage - those two image blocks are posters that I've made to take up the full screen. After some some more research I landed on the below code to made the button (changed to be logos) above the description so I'm all good now, thank you!
.design-layout-poster .image-button-wrapper {
margin-top: -47%;
}
@media screen and (max-width: 640px) {
.design-layout-poster .image-button-wrapper {
margin-top: -85%;
}
}
}
