• Not supported by Vector 2022 unless JavaScript is enabled in any namespace
  • Will be supported in 1.43.0-wmf.24 via T374499
• Not consistent with other message boxes across the MediaWiki interface

• Currently not supported by opt-in skins ( legacy Vector, Modern, Timelesswithout Category gadget loading Codex.) in pages which do not have form elements on page load (e.g. pages that do not load mediawiki.htmlform.codex.styles)
• Supported by Minerva
• Supported by Vector 2022
• In future, compatible will be compatible with any stable Codex that is created by https://phabricator.wikimedia.org/T363607
• Consistent with other message boxes across the MediaWiki interface
• May require markup tweaks in future in line with Codex updates.

At time of writing (17th September) the following pages are impacted.

• JS / CSS in user or MediaWiki namespace - 48 pages
  • This is officially supported.
  • ACTION: can safely use the new markup in all skins with Codex module dependency.
  • for support in non-default skins you may need to load dependency to style messages (mediawiki.htmlform.codex.styles is recommended)
• Content - 276 pages
  • MediaWiki namespace - 132 pages
    • This is officially supported under the assumption the message is used in an interface where message boxes are supported e.g. a page which has form elements.
    • ACTION: can safely use the new markup in all skins.
    • For messages used in different contexts, please see "other".
  • Help - 10 pages
    • Consider using a screenshot. If not, follow recommendation for other.
  • Other 134 pages
    • no action required for now
    • you can optionally migrate to Codex markup or alternative template if support is not essential for opt-in skins (Vector,Timeless,Monobook). You can also load associated styles via a template gadget
