Got it — that’s the Wikipedia Main Page HTML (Vector 2022 skin). Here’s a fast, useful map + tips you’ll likely want if you’re auditing, reusing, or scraping it.

What’s in here (structure)

  • Head: MediaWiki ResourceLoader setup, OG tags, Apple icons, canonical, Atom feeds, preconnect to upload.wikimedia.org, fixed viewport width=1120.
  • Skin/UI: Vector 2022 header, sticky header, typeahead search, pin-able “Main menu” and “Page tools.”
  • Main content blocks:
    • Top banner: “Welcome to Wikipedia,” live editor/article counts.
    • From today’s featured article
    • Did you know …
    • In the news
    • On this day
    • Today’s featured picture
    • Other areas / Sister projects
    • Wikipedia languages: big interlanguage directory (352 langs).
  • Footer: CC BY-SA 4.0 + Terms/Privacy links, “Powered by MediaWiki,” mobile view switch.

Notable implementation details

  • MediaWiki modules: RLCONF/RLPAGEMODULES bootstrap CSS/JS bundles; most JS is deferred through /w/load.php.
  • Accessibility: skip link, ARIA labels on navs, heading hierarchy per section, alt text on images.
  • Performance: preconnect to uploads; images via upload.wikimedia.org with multiple thumbs; JS is modular via ResourceLoader. (Viewport is fixed to 1120px to match Vector layout.)
  • Dynamic data: counts and sections are server-rendered; page is cached (parser-cache metadata at bottom comment).

If you plan to reuse or republish

  • Text license: CC BY-SA 4.0 — you must attribute and share-alike.
  • Images: each file has its own license (some CC, some public domain, some restricted) — check the file page before reuse.
  • Trademarks: “Wikipedia®” and the puzzle-globe are WMF trademarks; don’t imply endorsement.
