## What it is
A tiny (1kb) jQuery plugin that provides cross-browser, OS X Lion-style overlay scrollbars for web pages while preserving native scrolling behavior like inertia and input-device support. It hides real scrollbars and renders custom fade-in/out, draggable scrollbars via CSS3 animations.

## Use cases
- customize scrollbars to look like OS X Lion overlay scrollbars
- hide native scrollbars but keep native scrolling velocity and inertia
- show scrollbars only on hover over scrollable content
- make draggable custom scrollbars work across IE7+, Firefox, Chrome, and Safari
- style scrollbars for custom form widgets without breaking scrolling
- adapt scrollbar display when a container is dynamically resized

## When to choose
- you need Lion-style overlay scrollbars in a legacy jQuery codebase
- you must support old browsers like IE7+ with custom scrollbars
- you want a minimal 1kb scrollbar solution that preserves native scroll physics

## When to avoid
- you only target modern browsers with native CSS scrollbar styling
- your project does not use jQuery
- you need an actively maintained library with a license

## Facets
- artifact type: library
- maturity: abandoned
- function: ui-components, animation
- domain: frontend, web-development
- platform: browser, cross-platform
