Create “Back to Top” Icon in Hello Theme & Elementor

Yesterday, a client hired me to create “back to top” icon in Hello Theme and Elementor.

After a few hours of reading some articles on docs.elementor.com and Internet, I used the code from W3schools (thank to tester: Yasien)

Features

  • Only appear when scroll down
  • Disappear when scrolled up near the top of the site

1. Add HTML widget to Footer

2. Paste the HTML & JavaScript Code

Paste the following code to Content > HTML Code

<i class="fas fa-chevron-circle-up" onclick="topFunction()" id="kltop" title="Go to top"></i>
<script>
    //Get the button:
mybutton = document.getElementById("kltop");
// When the user scrolls down 20px from the top of the document, show the button
window.onscroll = function() {scrollFunction()};
function scrollFunction() {
  if (document.body.scrollTop > 20 || document.documentElement.scrollTop > 20) {
    mybutton.style.display = "block";
  } else {
    mybutton.style.display = "none";
  }
}
// When the user clicks on the button, scroll to the top of the document
function topFunction() {
  document.body.scrollTop = 0; // For Safari
  document.documentElement.scrollTop = 0; // For Chrome, Firefox, IE and Opera
}
</script>

3. Paste the CSS code to style “back to top” icon

Advanced > Custom CSS > Paste the following CSS code

#kltop {
    display: none;
    position: fixed;
    bottom: 20px;
    right: 30px;
    z-index: 99;
    border: none;
    outline: none;
    cursor: pointer;
    border-radius: 10px;
    font-size: 40px;
    color: #a67c00;
}
