Disable Browser and Element Scrollbars While Preserving Scrolling Functionality

When it comes to web design, sometimes you may encounter the need to disable scrollbars to achieve a certain aesthetic or functional goal, but simultaneously preserve the ability for users to scroll the content using their mouse wheel or arrow keys. Here's how you can tackle this challenge:

Hiding Scrollbars

To hide scrollbars from specific div elements or the entire document body, employ the following CSS rule:

overflow: hidden;

This will effectively conceal any scrollbars for the targeted element.

Emulating Scrolling with JavaScript

To enable scrolling functionality without visible scrollbars, you'll need to utilize JavaScript:

Mouse Wheel Scrolling

For mouse wheel scrolling, you can leverage the "mousewheel" event and adjust the scrollTop value of the target element dynamically. For instance, using jQuery:

$("#example").bind("mousewheel", function(ev, delta) {
    var scrollTop = $(this).scrollTop();
    $(this).scrollTop(scrollTop - Math.round(delta));
});

Arrow Key Scrolling

To emulate scrolling via arrow keys, bind a "keydown" event listener to the document (if needed) and adjust the scrollTop and scrollLeft accordingly. Remember to use "keydown" instead of "keypress" due to IE compatibility issues.

Example

Here's a practical example combining both mouse wheel and arrow key scrolling:

<div></div>
