Reply To: Slider revolution not mobile friendly

Hi,
I’m trying to tweak the placement of the background using the sliders CSS, but it doesn’t seem to be working. Can you please help?

I’m adding the following css:

@media only screen and (max-width: 700px){

ul.tp-revslider-mainul .slotholder .tp-bgimg.defaultimg{

background-position: -1100px center !important;
}
}
