Page background image not working

As per client requests, many of the courses that I developed had page background images. The below javascript worked pretty well for the purpose (thanks to Russell Killips).

$(".top-ui-bg").css("background-color", "transparent");
$(".area-primary").css("background-color", "transparent");
$(".cs-slide-container").css("background-color", "transparent")
$(".bottom-ui-bg").css("background-color", "transparent");

var x = document.getElementById("presentation");
x.style.backgroundImage = "url('Cover.jpg')";
x.style.backgroundSize = "cover";
x.style.backgroundRepeat = "no-repeat";

 

However, with the recent updates, there is no way to include a background image to Storyline 360. The above javascript does not work any longer and when I made the slide to 100% transparent in dark theme, the slide shows in white colour.

Story file and published output are attached herewith.

Appreciate any help to solve this...

My solution, rewrite the code.

I used the following in the other example you sent me through LinkedIn:

//Code to change the html background to an image
document.body.style.backgroundImage = "url('cover.jpg')";

var tempID = document.querySelector("[id^='uniqueDom']");
tempID.setAttribute("fill-opacity", "0")
;
var tempID = document.querySelector("[id^='slide-bg']");
tempID.setAttribute("fill-opacity", "0");

To avoid most of this custom code, you can just use (or switch to) the classic player and in the player properties window set the player background components to 100% Transparency. 
Then the only code you need is to set the background image to the page.

As the javascript in the description no longer works, the below is the updated code:

document.getElementById("slide").style.backgroundColor = "transparent";
var x = document.getElementById("wrapper");
x.style.backgroundSize = "cover";
x.style.backgroundRepeat = "no-repeat";
x.style.backgroundPosition = "center";
x.style.backgroundImage = "url(Cover.jpg)";

Thank you so much Russell Killips for sharing this updated code.
