Disable Modul position for display in Smartphone

i have changed to:

@media (max-width: 512px){

.mp_advert1 {

height: 0px!important;
width: 0px!important;
overflow: hidden;

}
}

but nothing changed

any idea what i can do?

Well we helped you as much as we can, module position is really not visible in mobile view. Despite it's unvisible, google tool see it's primary dimensions (we changed them under 512 to 0px x 0px), but it's probably because their tool works on that way.

On other way this can be done through scripts but requires time and it's taken as paid job.
