[20:33:40] <jacksonchen666>	 hi, how do i add mobile-only global CSS with Extension:MobileFrontend? the MW wiki page about it says something about MediaWiki:Mobile.css but that's MW <=1.40 with no info on later versions
[20:36:00] <jacksonchen666>	 (XY problem: i'm using Extension:DynamicPageList4 and want multiple columns on desktop view, but single column on mobile due to layout and space reasons. currently multiple columns require a CSS workaround (https://dpl4.wikitide.org/wiki/Controlling_output_format#columns), so i'm basically trying to selectively apply that workaround CSS)
