Hi guys,
So I decided to change the default theme to cyberpunkish.css to make this instance look different from a default lemmy instance.
If a lot of people tell me this is a shitty idea and I should not do this, I will revert it. Just wanted to give this instance a style of its own. The default theme is still there under lemmy_default.css if you prefer it.
Let me know if you have strong feelings about it, one way or the other!
If you want to tweak the appearance of a website via custom CSS (and optionally share it), there's the Firefox and Chrome extension Stylus.
https://addons.mozilla.org/en-US/firefox/addon/styl-us/
https://chromewebstore.google.com/detail/stylus/clngdbkpkpeebahjckkjfobafhncgmne
It's really intended for re-theming individual sites, though -- I don't think that it has a way to publish your CSS changes for lemmy.today's theme so that users of any other lemmy instance could automatically find them using Stylus, just manually import them. You could upload them somewhere
and it looks like some people have done so, as with this GitHub archive of Lemmy themes
but it doesn't natively provide a feature to "search for custom themes published for any Lemmy instance".
