It's a common request and can email the moderators (dang) https://news.ycombinator.com/item?id=23197966 There might be a reason why it hasn't happened yet or it's simply not pressing compared to keeping the website running.

I use the 'Dark Reader' Firefox extension as work-around.

It is just cheaper to create an app/website in Dark Mode these days. The loud minority is placated and the rest don't care.

It's probably not gonna happen, guys.

> prefers-color-scheme: dark

i vote to keep it as it is thank you very much

look into the browser extension Stylus (only changes CSS) or the one named "Dark Reader" (which also only changes CSS to my understanding)
