Skin talk:DarkCosmos/Flow

Pretty much all "dark" modifications should be implemented as a theme via the Theme extension; this requires minimal changes to the parent skin (usually merely the addition of a ThemeModules definition to its skin.json file; see Skin:Gamepress for an example) and if that's not doable, it can be done in Theme.

By implementing this as a theme, there's less maintenance overhead and less unnecessary code duplication, which results in less maintenance burden and makes it easy to update the theme if and when necessary, instead of having to sync various PHP-level changes and whatnot.

I am using DarkCosmos with mediawiki 1.35 and dropdown menus such as the one that should open when clicking on the username do not appear when the site is in "desktop" mode. Things are fine in "mobile" mode, i.e. on small windows. Any idea how to fix this? I tried to checkout the patched version of the skin mentioned at https://github.com/Killarnee/DarkCosmos/issues/2 , but it did not help with this particular issue.

The skin downloader doesn't seem to have this skin; you have to download it from the Git repo.
