But someone has to pay the bills, and sponsors are paying for it. I insist on not turning Code Boxx into a "paid scripts" business, and I don't "block people with Adblock". Every little bit of support helps.

1) THE HTML

<!-- (A) DUMMY CONTENT -->
<div id="top">Some content.</div>
 
<!-- (B) BACK TO TOP -->
<a id="backtop" href="#top">
  <svg xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24"><path d="M0 16.67l2.829 2.83 9.175-9.339 9.167 9.339 2.829-2.83-11.996-12.17z"/></svg>
</a>

1. Just give an id to the very first element on your page.
2. Insert the “back to top” button at the bottom of the page.

P.S. I have directly inserted an <svg> up arrow into the button. You can use an image if you want, or check out this list for other SVG arrows.

 

2) THE CSS – PLACE BUTTON AT BOTTOM

/* (A) SMOOTH SCROLL */
html { scroll-behavior: smooth; }

/* (B) BACK TO TOP BUTTON */
#backtop {
  position: fixed; bottom: 20px; right: 20px;
  width: 50px; height: 50px; border-radius: 50%;
  display: none;
  justify-content: center; align-items: center;
  background: #dedfff;
}

1. This should be self-explanatory, adds smooth scroll animation to the page.
2. This may seem to intimidating to beginners, but keep calm and study slowly.
   • position: fixed; bottom: 20px; right: 20px; Place the button at the bottom right corner.
   • width: 50px; height: 50px; border-radius: 50%; Create a round button.
   • display: none; Hide the button by default, we will show it only when the user has scrolled down sufficiently.
   • justify-content: center; align-items: center; Center the arrow in the circle.
   • background: #dedfff; Well, the background color.

 

 

3) THE JAVASCRIPT – DETECT SCROLL

// (A) SHOW/HIDE BUTTON ON SCROLL/RESIZE
const togtop = () =>
  document.getElementById("backtop").style.display = window.scrollY >= 100 ? "flex" : "none";
 
// (B) LISTEN TO SCROLL + RESIZE
window.addEventListener("scroll", togtop);
window.addEventListener("resize", togtop);

TLDR – Show the “back to top” button only when the user has scrolled down at least 100 pixels. Feel free to adjust this.
