A JavaScript polyfill implementing the CSSOM Scroll Behavior specification, adding smooth scrolling support for window.scroll, window.scrollTo, window.scrollBy, and Element.scrollIntoView in browsers that lack native support. It detects native support and only patches when necessary.

Use cases

• add smooth scrolling to anchor links in older browsers
• polyfill scrollIntoView smooth behavior in Safari or IE
• make window.scrollTo animate smoothly cross-browser
• support scroll-behavior CSS spec in unsupported browsers
• smooth scroll to page sections on click

When to choose

• you must support older browsers like IE9+, Safari 6+, or Edge 12+ that lack native scroll-behavior
• you want a spec-compliant polyfill rather than a custom animation library
• you need a tiny drop-in fix that only activates when native support is missing

When to avoid

• your target browsers all natively support CSS scroll-behavior (modern Chrome, Firefox, Opera)
• you need advanced scroll animation features beyond the spec, like easing or callbacks
• you need a full-featured smooth scroll library with custom controls
