A CSS styleshoot for Forgejo that makes it look and feel a bit more like GitHub.
This started off with me just changing colors, but quickly grew to also adjusting various parts of the UI to be more GitHub-like as well. The most obvious one is probably the top bar contents being inlined (except for the home page), which saves a decent amount of screen real estate, but there's a ton of tweaks all across the UI to make it more in line with GitHub.
It definitely doesn't cover everything, nor is it perfect, but it's close enough for my use, and probably most people, though further suggestions/tweaks to the CSS are welcome.
I recommend setting Settings -> Appearance -> Default theme to gitea-auto, as that's what this was developed against. Most focus went into the dark theme, but it was sanity-checked in light mode as well.
I'm personally using the FireMonkey extension for Firefox to set the theme, but should work with any CSS changing addon in your browser of choice.
