How can i use handlebars data in front end js variable

I'm trying to create the exact effect below (but on a pop up modal). I got it to work so far but the html is broken (img tags not closed). And if I fix the img tags the perspective effect goes away. Can someone explain why and show me how to fix it please? I have perspective:100px on the main wrapper as per this article https://css-tricks.com/almanac/properties/p/perspective/..

var lFollowX = 0,
    lFollowY = 0,
    x = 0,
    y = 0,
    friction = 1 / 30;
function moveBackground() {

x += (lFollowX - x) * friction;

y += (lFollowY - y) * friction;
translate = ‘translate(’ + x + 'px, ’ + y + ‘px) scale(1.1)’;
$(‘.bg’).css({

‘-webit-transform’: translate,

‘-moz-transform’: translate,

‘transform’: translate

});
window.requestAnimationFrame(moveBackground);

}
$(window).on(‘mousemove click’, function(e) {
var lMouseX = Math.max(-100, Math.min(100, $(window).width() / 2 - e.clientX));

var lMouseY = Math.max(-100, Math.min(100, $(window).height() / 2 - e.clientY));

lFollowX = (20 * lMouseX) / 100; // 100 : 12 = lMouxeX : lFollow

lFollowY = (10 * lMouseY) / 100;
});
moveBackground();

body {

height: 100vh;

}
.wrap {

background-color: #0F2044;

-webkit-perspective: 100px;

perspective: 100px;

height: 100%;

position: relative;

overflow: hidden;

}

.wrap .bg {

width: 100%;

height: 100%;

position: absolute;

top: 0;

left: 0;

z-index: -1;

-webkit-transform: scale(1.1);

transform: scale(1.1);

}
