How to change revolution slider background color opacity
.rev_slider .slotholder:after {
width: 100%;
height: 100%;
content: "";
position: absolute;
left: 0;
top: 0;
pointer-events: none;
background: rgba(255, 255, 255, 0.5);
}
Can do the same for section background image, just need to add a class to the container and put the .classname in place of .rev_slider .slotholder
