Topic on Extension talk:DarkMode

gadget:dark-mode.css is available

I don't see an option to enable a dark mode in "VECTOR-2022" theme on www.mediawiki.org.

Is this option no longer supported?

add @import "https://en.wikipedia.org/w/index.php?title=MediaWiki:Gadget-dark-mode.css&action=raw&ctype=text/css"; to special:mypage/common.css and reload

This solution help resolving my problem.

Thanks :)
