Website Anchor Smooth Scroll

When a visitor clicks a link that points to a section on the same page (a link starting with #), the page no longer jumps straight to that section. Instead it glides smoothly down or up to it, stopping slightly above the target so the section heading stays visible.

• The smooth scrolling is added to the website's frontend assets, so it applies to all website pages automatically.
• It only affects internal anchor links; normal links to other pages are untouched.
• After the scroll finishes, the address bar is updated with the anchor, so the link can still be shared or bookmarked.
• The module also ships a demo page called "Anchor smooth scroll demo", published on the website and linked from the main website menu, with buttons that scroll to the top and bottom of the page so you can try the effect.

No new business models, menus, or settings screens are added for regular use; the only visible additions are the smooth scrolling behaviour and the demo page. It touches the website frontend assets and the website page and menu records used for the demo.
