Nicescroll as a Greasemonkey plugin: http://userscripts.org/scripts/show/119910 (freezed)

Nicescroll is a jQuery plugin, for nice scrollbars with a very similar ios/mobile style.

• HORIZONAL scrollbar support!
• It supports DIVs, IFrames, textarea, and document page (body) scrollbars.
• Compatible with all recent desktop browsers and older: Chrome, Firefox, Edge, IE8+, Safari (win/mac), Opera. (all A-grade browsers)
• Compatible with mobile devices: iPad/iPhone/iPod, Android 4+, Blackberry phones and Playbook (WebWorks/Table OS), Windows Phone 8 and 10.
• Compatible with all touch devices: iPad, Android tablets, Window Surface.
• Compabible with multi-input devices (mouse with touch or pen): Window Surface, Chrome Desktop on touch notebook.
• Compatible with 2-directional mice: Apple Magic Mouse, Apple Mouser with 2-dir wheel, PC mouse with 2-dir wheel (if browser support it).

What you get: customizable and scrollable divs with momentum for iPad and consistent scrollable areas for all desktop and mobile platforms.

Sexy zoom feature: you can "zoom in" on the content of any nicescroll enabled DIV. Nice to use and nice to see: all the content of the DIV in fullscreen mode. It works on desktop (double click on div) either in mobile/touch devices using the pinch gesture.

On modern browsers hardware accelerated scrolling has been implemented. Using animationFrame for smoother and cpu-saving scroll animations. (when browser supports)

"Use strict" tested script for maximum code quality. Bower and AMD ready.

Warning for IE6/IE7 users: support for your browser has been deprecated. (Why do you still use this? Please upgrade to a more stable and modern browser)

FEATURES

• Simple installation and activation: functions with NO modification of your code. (some exceptions can happen, in which case you can write to me.)
• Very stylish scrollbars with no occupation on your window: original browser scrollbars need some of page space and reduces window/div usable width.
• You can style main document scrollbar (body) too! (not all devices/browsers support this feature yet)
• You can scroll by dragging the cursor, mouse wheel (speed customizable), keyboard navigation (cursor keys, pagup/down keys, home/end keys) on all browsers.
• Scrolling is smooth (like modern tablet browsing). Speed is customizable.
• Zoom feature.
• Hardware accelerated scroll (where available).
• Animation frame support for smooth scrolling and cpu-saving.
• Dragging scroll mode with scrolling momentum (like touch devices).
• Tested for all major mobile and desktop browser versions.
• Support for touch devices.
• Support for multi-input devices (MSPointer/Pointer support).
• Compatible with many other browsers and webkit derivatives!
• Scrollbar has a lot a customizable features.
• Native scroll events are working.
• Fully integrated with jQuery.
• Compatibile with jQuery UI, jQuery Touch, jQuery Mobile

DEPENDENCIES

jQuery is required to be included in your scripts. Works with jQuery 1.x / 2.x / 3.x branch (slim version don't works)

• INSTALLATION Put loading script tag after jquery script tag and loading the zoom image in the same folder of the script:

<script src="jquery.nicescroll.js"></script>

When using the zoom feature, copy "zoomico.png" in to the same folder as jquery.nicescroll.js.

• HOW TO USE

ALWAYS Initialize nicescroll in a (document) ready statement.

// 1. Simple mode, it styles document scrollbar:
$(function() {  
    $("body").niceScroll();
});

// 2. Instance with object returned:
var nice = false;
$(function() {  
    nice = $("body").niceScroll();
});

// 3. Style a DIV and change cursor color:
$(function() {  
    $("#thisdiv").niceScroll({cursorcolor:"#00F"});
});

// 4. DIV with "wrapper", formed by two divs, the first is the vieport, the latter is the content:
$(function() {
    $("#viewportdiv").niceScroll("#wrapperdiv",{cursorcolor:"#00F"});
});

// 5. Get nicescroll object:
var nice = $("#mydiv").getNiceScroll();

// 6. Hide scrollbars:
$("#mydiv").getNiceScroll().hide();

// 7. Check for scrollbars resize (when content or position have changed):
$("#mydiv").getNiceScroll().resize();

// 8. Scrolling to a position:
$("#mydiv").getNiceScroll(0).doScrollLeft(x, duration); // Scroll X Axis
$("#mydiv").getNiceScroll(0).doScrollTop(y, duration); // Scroll Y Axis
