How To Create a Scroll To Top Button

Step 1) Add HTML:

Create a button that will take the user to the top of the page when clicked on:

Example

Step 2) Add CSS:

Style the button:

Example

#myBtn {
display: none; /* Hidden by default */
position: fixed; /* Fixed/sticky position */
bottom: 20px; /* Place the button at the bottom of the page */
right: 30px; /* Place the button 30px from the right */
z-index: 99; /* Make sure it does not overlap */
border: none; /* Remove borders */
outline: none; /* Remove outline */
background-color: red; /* Set a background color */
color: white; /* Text color */
cursor: pointer; /* Add a mouse pointer on hover */
padding: 15px; /* Some padding */
border-radius: 10px; /* Rounded corners */
font-size: 18px; /* Increase font size */
}

#myBtn:hover {
background-color: #555; /* Add a dark-grey background on hover */
}

Step 3) Add JavaScript:

Example

// Get the button:
let mybutton = document.getElementById("myBtn");

// 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
}
