Adding scroll down button to Shopify custom theme - shopify

Question

I am customizing shopify motion theme. I added a scroll down svg on bottom of the slider. But having problem with scrolling down to the next section
I have added the scroll down button with that code;
div.hero__image-wrapper:after {
content: url({{ "icon-scroll-down.svg" | asset_url }}) ;
position: absolute;
display: block;
z-index: 34560;
bottom: 20px;
left: 48%;
font-size: 2em;
border-radius: 1em;
font-weight: bold;
border: 3px solid gray;
padding: 0.1em 0.1em 0;
animation-name: color_change;
animation-duration: 3s;
animation-iteration-count: infinite;
animation-direction: alternate;
}
#keyframes color_change {
0% { color: gray; bottom:20px;}
10% { color: black; bottom:10px;}
20% { color: gray; bottom:20px;}
100%{ color: gray; bottom:20px;}
}
But currently it's only an icon. I need to make it scroll to down

I would do it with JS instead. Let's assume your button is an actual element instead of pseudo ::after:
<div class="scroll-down-button"></div>
.scroll-down-button {
// whatever style you prefer
}
Then the JS code would look like this:
(function() {
// Get the button element
var button = document.querySelector('.scroll-down-button');
// Get current section
var currentSection = button.closest('.shopify-section');
// Get next section (the very next element after current section container)
var nextSection = currentSection.nextSibling();
// Get the coordinates of the next section
var nextSectionCoordinates = nextSection.getBoundingClientRect();
// Get the top Y axis coordinates of next section
var nextSectionTop = nextSectionCoordinates.top;
// Scroll to the top of next section (0 means no scroll on X axis)
window.scrollTo(0, nextSectionTop);
})();
The above is not tested, so let me know if it doesn't work or you can console.log any values. You should get the idea though!
