CSS for mobile - declension and other tables
Fragment of a discussion from User talk:Rua
It's strange that it shows both parts of the table at all times. I would appreciate it if you could report this at the Grease Pit with any information on which tables it happens with. Currently, at least Dutch verbs and adjectives, Finnish nominals and verbs, Veps nominals and verbs, Northern Sami nominals and verbs, Proto-Indo-European nominals and verbs, Latin verbs, Proto-Italic verbs use the new system. There may be more I forgot about.
In case you're good with JavaScript, the file MediaWiki:Gadget-legacy.js, line 645 onwards.
