## What it is
A pure JavaScript plugin for creating smart, high-performance sticky sidebars that stay visible while scrolling. It works with sidebars taller or shorter than the viewport, integrates a resize sensor, and optionally works as a jQuery/Zepto plugin.

## Use cases
- make a sidebar stick while scrolling
- keep a table of contents visible on long pages
- handle a sticky sidebar taller than the viewport
- avoid scroll jank with a fixed sidebar
- add sticky sidebar to a jQuery site
- recalculate sidebar position on container resize

## When to choose
- you need a dependency-free, performant sticky sidebar in vanilla JS
- your sidebar may be taller or shorter than the viewport
- you want jQuery/Zepto integration
- you need resize-aware sidebar recalculation

## When to avoid
- you use a modern CSS framework where position: sticky suffices
- you need a React/Vue component rather than a DOM plugin
- you need active development and frequent updates

## Facets
- artifact type: plugin
- maturity: maintenance
- function: ui-components, animation
- domain: frontend, web-development, web-design
- platform: browser
- tags: sticky-sidebar, scrolling, jquery-plugin, zero-dependencies, performance, javascript
