Remove black frame around SCORM on LMS

Basically this is set in the html and css files Articulate uses to publish a project in Storyline360.
These 2 lines of Javascript code do the trick.

/*
You always need to select an element. In this case the body.
With the browser tools you can find the element you want to target
*/
let StorylineBg = document.querySelector("body");

//As GSAP is buildin to SL360, its easy to set the color
gsap.set(StorylineBg, {backgroundColor:"#F29455"});

Offcourse you can change anything this way. Just test and see with the browser tools and the console.

Here is a sample.

And the Storyline attached.
