ウィキペディアの編集者の要請により、MediaWikiに新機能を追加しました. タグを使って作成した出典一覧（ウィキによって典拠や脚注と呼ぶこともある)が長くなると、表示を自動で2段以上に組むようになりました. 段の数は、閲覧者が使うモニターの大きさに応じて決まります. これはen:accessibilityを高め、大部分の閲覧者には出典の参照が楽になるはずで、特に画面の幅が狭いあるいは広い場合に有効です. 出典一覧が 短い場合は影響を受けません.

この機能が有効なウィキでは、今までどおり タグを使うと、出典の多いページであれば出典の表示が変わります. もしも出典一覧を段に分けず、従来の表示にしたい場合には 、次のウィキ文のコードを使います. .

日程
The server-side software will change on the normal deployment train during the week of 14 March 2017. However, the effect will not normally be visible (except on MediaWiki.org where it is responsive by default ) until it is manually enabled for your particular wiki. WMF-hosted wikis that want this feature working locally can request a config change to enable it.

After the software is deployed, but before it is enabled on your wiki, you can manually invoke the feature on individual pages by using this wikitext code:   instead of the plain    tag or a local template.

 * Wikiquotes: Monday, 24 July 2017
 * Wiktionaries and Wikivoyages: Monday, 11 September 2017 (the English Wiktionary is already done.)

Interaction with local templates
Some Wikipedias have been using local templates such as to create columns or add other formatting. These templates should be updated (or their use deprecated as redundant) before this change is manually enabled at your local wiki.

If you want to improve accessibility
Consider defining the default behavior for the template as being the default behavior for the  tag and deprecating or removing parameters that define a fixed number of columns, regardless of screen size.

If you want no changes to the template's current behavior
will automatically wrap the list in . With the feature enabled by default, any list with more than 10 references will also get the class . In this mode, the references list is automatically split over multiple columns based on the available space on the screen. E.g. on narrow screens 1 or 2 columns, on wider screens 2 or 3. Given that this happens automatically, it is no longer necessary for editors to manually enable/disable the columns mode of a template.

Remember also that other customisations for the references list are best applied directly to the   CSS selector in your wikis' MediaWiki:Common.css. Many wikis customise the font-size this way, for example. (No need to manually code it through a template). In case a DIV wrapper is needed for certain styles, the   CSS selector will apply to all references lists produced by   regardless of whether the columns were dynamically activated.

For compatibility with fixed-column layout, you can have the reflist and refhead templates make sure responsive mode is turned off with  when a fixed number of columns is specified. You may also want edit relevant layout rules in your wiki's MediaWiki:Common.css to only match  elements without a wrapping   parent in order to avoid repeated definitions of multi-column layout. This can be done in the CSS using e.g. a direct descendant  operator.

Requesting this feature
To request that this feature be enabled at your local wiki, please file a Phabricator task by filling in this pre-formatted Phabricator task.

Alternatively, leave a message on the talk page. Please include a link to any local discussions or relevant templates in your requests.
