CSS: Adding parallax to 7.1 Squarespace site

Have you chosen a 7.1 template and miss the parallax feature?

Well there's a quick fix to help. It's not as streamlined and smooth as the natural parallax of 7.0 templates, but it's a good quick fix until Squarespace hopefully re-introduces the feature.

Place the below CSS in your SETTINGS > ADVANCED > CODE INJECTION section.

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script src="https://cdn.jsdelivr.net/parallax.js/1.4.2/parallax.min.js"></script>

<script> 
  $('.has-background:not(:has(.sqs-video-background))').each(function() {
    var findImage = $(this).find('.section-background img');
    var imgUrl = findImage.data('src');
    var dimensions = findImage.data('image-dimensions');
    var imgWidth = dimensions.substr(0, dimensions.indexOf('x'));
    var imgHeight = dimensions.substr(dimensions.indexOf('x') + 1);
    $(this).parallax({
        imageSrc: imgUrl,
        naturalWidth: imgWidth,
        naturalHeight: imgHeight,
        speed: 0.1,
    })
});
document.getElementsByTagName("body")[0].onresize = function() {
    setTimeout(function() {
        jQuery(window).trigger('resize').trigger('scroll')
    }, 100)
}; 
</script>

<style>.has-background{background-color:transparent!important}.has-background .section-background{background-color:transparent!important}.has-background .section-background img{visibility:hidden!important}.has-background.background-width--inset{margin:4vw;padding:0!important}.has-background.background-width--inset:not(.content-collection):not(.gallery-section) .section-background{top:0!important;right:0!important;bottom:0!important;left:0!important}</style>

You can alter the speed up to 1. I like a 0.1 because you can tell there's a parallax instead of it appearing as if it's a slow loading speed.
