tilsmooth scrolling

Browser’s automatic scrolling behavior has traditionally been very jumpy, with developers needing to write custom JavaScript code to simulate a smooth scroll. However thanks to the smooth scrolling specification, browsers over the years have adopted an API for CSS and JavaScript to natively smooth scroll.

When clicking an anchor link, the transition be can be smoothed by adding the scroll-behavior rule to the root element.

:root {
  scroll-behavior: smooth;

For navigating to a specific page location using window.scrollTo() or similar methods, provide an options object instead of explicit coordinates.

// Old way
window.scrollTo(0, 100)

// Smooth way
window.scrollTo({ top: 100, behavior: 'smooth' })
