fix(docs): remove scroll-smooth to fix navigation scroll position by christopherkindl · Pull Request #1694 · vercel/workflow

christopherkindl · 2026-04-10T23:45:06Z

Summary

Removes the scroll-smooth CSS class from the <html> element in the docs root layout
The global smooth scroll was causing Next.js navigation scroll-to-top to animate instead of jumping instantly, making cross-page links (e.g. "World Interface Docs" on /worlds) appear stuck at the previous scroll position
Components that need smooth scrolling (e.g. the "Scroll to top" button) already use behavior: 'smooth' explicitly and are unaffected

…sition The global `scroll-smooth` CSS class on <html> caused Next.js navigation scroll-to-top to animate instead of jumping instantly, making cross-page links appear stuck at the previous scroll position.
