To draw attention to the user, I need the range slider button to float up and down until hovered, or clicked on by the user.

Then, when hovered it pauses its vertical movement.

When clicked on it altogether stops.

The max value for the range slider is 100, the min is 0, and the default is 50.

So, it should float at the position of 50.

What I have tried:

The following code is what I have, but instead of floating by default, the range slider appears hidden... any suggestions?

Here's the HTML:
<pre><div id="slider-container">
  <input type="range" id="myRange" min="0" max="100" value="50">

Here's the JS:
var slider = document.getElementById("myRange");
var container = document.getElementById("slider-container");

// Add floating class by default

// toggle floating class on hover
slider.addEventListener("mouseover", function() {
  if (slider.classList.contains("floating")) {
  } else {

// remove floating class on click
slider.addEventListener("click", function() {
  if (slider.classList.contains("floating")) {

Here's the CSS:
#slider-container {
  position: relative;
  /* other styling */

#myRange::-webkit-slider-thumb {
  transition: all 0.3s ease-in-out;
  /* other styling */

#myRange.floating::-webkit-slider-thumb {
  position: relative;
  top: -30px;
  animation: float 3s ease-in-out infinite;

@keyframes float {
  0% {
    transform: translateY(0);
  50% {
    transform: translateY(-30px);
  100% {
    transform: translateY(0);

you may need "z-index" for a higher stack with the animated element.

and to go all over the screen : "position:absolute;" with "top" / "left" coordinates.

if you stay in the container , use the 'width' and 'height' of the container, and those for the moving elements.

Can you elaborate on this?

The above comment is really answering the question, but it is a bit of a guessing game - is the "slider-container" the parent or the child element.

If parent, your position should be absolute and all other children as relative.

Either remove this for now to test and I am sure your scroll will display.
