image overlap a section fluid engine 7.1

Hey! i don't know why this has stopped working as it was fine this morning.

i had an overlapping image but now the section below is showing above / on top of the image.

i've tried z-index but no luck. 

here's current code:

@media screen and (min-width:768px) {
#block-dcd7158a35cf1cf082ed {

transform:translateY(50%);
z-index:9999!important;}
}
