Change Revolution Slider's height for mobile devices through initialization

Question

Please refer to the top hero section on this page for the example of Revolution Slider.

It's initialization code in this javascript file is:

function dz_rev_slider_5(){
    if(dzQuery("#rev_slider_11_1").revolution == undefined){
        revslider_showDoubleJqueryError("#rev_slider_11_1");
    }else{
        dzrevapi = dzQuery("#rev_slider_11_1").show().revolution({
            sliderType:"standard",
            sliderLayout:"fullscreen",
            dottedOverlay:"none",
            delay:9000,
            navigation: {
                onHoverStop:"off",
            },
            responsiveLevels:[1240,1240,778,778],
            visibilityLevels:[1240,1240,778,778],
            gridwidth:[1640,1640,778,778],
            gridheight:[768,768,960,960],
            lazyType:"none",
            parallax: {
                type:"mouse",
                origo:"enterpoint",
                speed:400,
              speedbg:0,
              speedls:0,
                levels:[5,10,15,20,25,30,35,40,45,46,47,48,49,50,51,55],
            },
            shadow:0,
            spinner:"spinner0",
            stopLoop:"off",
            stopAfterLoops:-1,
            stopAtSlide:-1,
            shuffle:"off",
            autoHeight:"off",
            fullScreenOffsetContainer: "",
            disableProgressBar:"on",
            hideThumbsOnMobile:"off",
            hideSliderAtLimit:0,
            hideCaptionAtLimit:0,
            hideAllCaptionAtLilmit:0,
            debugMode:false,
            fallbacks: {
                simplifyAll:"off",
                nextSlideOnWindowFocus:"off",
                disableFocusListener:false,
            }
        });
    }
}

I need to reduce the height of the slider by 30% for mobile devices. And by following this answer, I tried changing the value of gridheight from [768,768,960,960] to [768,768,672,672]. I also tried changing the value of autoHeight from "off" to "on". However, those tries do not work.

Answer 1

I guess all it needed was fullScreenOffset: "30%", which I found here: https://www.themepunch.com/revsliderjquery-doc/slider-layout/
