Scrollbar Hide: JavaScript

1. Create the custom scrollbar using CSS:

You'll need to style a custom scrollbar that visually hides the default scrollbar. This can be achieved by setting its width and height to zero and customizing the look using ::-webkit-scrollbar (for WebKit browsers) and ::-webkit-scrollbar-thumb.

/* Hide the default scrollbar for WebKit browsers (e.g., Chrome, Safari) */
body::-webkit-scrollbar {
  width: 0;
  height: 0;
}

/* Customize the look of the scrollbar thumb */
body::-webkit-scrollbar-thumb {
  background: transparent;
}

2. Prevent the default scrollbar from appearing in other browsers:

You can use the following CSS to ensure the default scrollbar doesn't appear in non-WebKit browsers (e.g., Firefox)

/* Hide the default scrollbar for non-WebKit browsers (e.g., Firefox) */
body {
  scrollbar-width: none;
}

Implement scrolling functionality using JavaScript:

Now, you'll need to handle scrolling using JavaScript. You can add an event listener to the document or a specific element and update the scroll position accordingly.

document.addEventListener('scroll', function() {
  // Get the scroll position
  var scrollTop = window.pageYOffset || document.documentElement.scrollTop;

  // Your custom scrolling logic here (if needed)

  // Update the scroll position
  // (You can also apply this to a specific element if needed)
  window.scrollTo(0, scrollTop);
});
