Step 1

Add the HTML & JavaScript code to your Squarespace site.

After you add the code, nothing will appear, this code is for the functionality of the Back To the Top button.

Settings > Advance > Code Injection > Footer

<!-- Scroll to the top -->
<script src="//"></script>
<link rel="stylesheet" href="" integrity="sha384-UHRtZLI+pbxtHCWp1t77Bi1L4ZtiqrqD80Kn4Z8NTSRyMA2Fd33n5dQ8lWUE00s/" crossorigin="anonymous">
<button onclick="topFunction()" id="myBtn" title="Go to top"><i class="fas fa-arrow-up"></i></button>
<!-- End Scroll to the top -->

<!-- Scroll to the top JS-->
   window.onscroll = function() {scrollFunction()};

   function scrollFunction() {
      if (document.body.scrollTop > 20 || document.documentElement.scrollTop > 20) {
         document.getElementById("myBtn").style.display = "block";
      } else {
         document.getElementById("myBtn").style.display = "none";

   function topFunction() {
      $('html,body').animate({ scrollTop: 0 }, 750);
<!-- End Scroll to the top JS-->
