Stickyfill is a JavaScript polyfill that emulates CSS `position: sticky` in browsers lacking native support, working in IE9+ and disabling itself where sticky is natively implemented. It is now unmaintained because all modern browsers support `position: sticky` natively.

Use cases

• make sidebar elements stick while scrolling in old browsers
• polyfill position sticky for IE9+
• keep a header pinned to the top of the viewport on scroll
• support sticky elements in legacy browser environments
• emulate sticky positioning without parsing CSS

When to choose

• you must support legacy browsers like IE9-11 that lack native position: sticky
• you need the most accurate sticky polyfill with native-like top and margin behavior

When to avoid

• you only target modern browsers, which all support position: sticky natively
• you need left, right, bottom, or combined sticky positioning
• your sticky elements live inside overflowed blocks
• you want an actively maintained dependency
