## Description

smoothscroll is a browser compatibility library and JavaScript polyfill that provides uniform smooth scrolling behavior across different web browsers. It functions as a frontend animation utility that intercepts standard scroll commands and replaces them with custom animation logic to ensure consistent navigation transitions.

The library includes a runtime feature detection tool that identifies native browser support for scroll properties, preventing redundant execution in modern environments. It synchronizes page position updates with the browser display refresh rate to prevent visual stuttering and jitter.

The tool covers a range of capabilities including the implementation of scrolling polyfills for older browsers and the optimization of frontend performance to maintain visual consistency during web navigation.
