[Theme: Arcade Basic] Scroll distance chang

Hi all, seen this posted before but never seen an answer to it.

I have a wedding website set up at https://www.sandbjudge.co.uk using the arcade basic theme. As you can see the home page has a button which is usually labelled “See More” which I have updated to say “RSVP”.

I want to update the scroll distance when that button is clicked to go to the bottom of the page but I cannot find where it is dictated in any of the theme files.

Using developer tools I can find the code that scrolls and it changes depending on the device.

For example if I go on it using my laptop now I find this in the developer tools:

<a href="#" id="more-site" class="btn btn-default btn-lg" data-scroll-to="267">RSVP</a>

Any help would be greatly appreciated.

Thanks,
