Wikipedia Smooth Scroll Userscript

A userscript that adds smooth scrolling to internal links on Wikipedia and its sister sites.

Features

• 🚀 Buttery-smooth scrolling for all in-page links (#anchor links)
• 🔄 Full support for browser history (back/forward buttons)
• 🌐 Works across all Wikimedia Foundation sites:
  • Wikipedia
  • Wiktionary
  • Wikibooks
  • Wikiquote
  • Wikivoyage
  • Wikisource
  • Wikinews
  • Wikiversity
  • Wikifunctions
• ✨ Handles dynamically loaded content
• 🛠️ Pure JavaScript - no dependencies required

Installation

1. Install a userscript manager:

   • Tampermonkey (recommended)
   • Violentmonkey
   • Greasemonkey

2. Click here to install:
   

   Or manually copy the script from the repository and add it to your userscript manager.

How It Works

The script:

1. Intercepts clicks on internal links
2. Prevents the default "jump" behavior
3. Animates smooth scrolling to the target element
4. Handles edge cases like:
   • Special characters in anchor IDs

Technical Details

• Uses scrollIntoView with behavior: 'smooth' for smooth animations
• Manages URL state to prevent native browser jumping
• Lightweight (less than 2KB without minification)

Possible Issues

• Some extremely old browsers may not support the smooth animation (will fall back to instant scroll)
