Discussioni sul web su quanti stati dovrebbero avere i toggle modalità diurna/notturna in app e siti. Cito il riassunto da Web Weekly 199:
How much controversy can there be around dark/light mode toggles? Turns out, a lot. Lea Verou kicked off a whole thing. People have opinions on these little two- or three-state toggles.
So, Lea started the discussion by arguing that website visitors don't care about dark mode toggles (I agree) and that they only reach for them when something's off.
A dark mode toggle is a temporary comfort adjustment. [...] It’s situational, it’s immediate, and it’s usually about the environment you’re in rather than a considered long-term stance on color schemes.
From there, she argues that a dark mode toggle should only have two options: the system preference (shown as dark or light) and the opposite. That's smart. Whenever things are different from the system, you can store the preference that's not the system default. If it matches their general settings, there's nothing to do, and if you go back to the system setting, you clear the preference. This approach seems reasonable to me at first sight.
Bramus disagreed, though.
When building these types of control, I think that one of the main goals here should be to keep things predictable for users.
And well, that's a strong point, too, I'd say. A little sun icon that actually means "system preferences" is a bit tricky to understand if you really care about light and dark modes. I tend to agree here, and it seems like a "Agree to disagree." case, but the whole community had feelings about this. Lea shared more feedback in a follow-up post. And it closed with a banger:
And then it dawned on me: all these persistent dark mode toggles I had seen, literally all of them have been on developer-facing sites!
And I think that's what I came to conclude, too. It's an interesting discussion to have but I really don't think normies care too much about two, three, or no dark/light mode states. Things can always be better and smoother, but for this case I think it's just us nerds who love discussing these things. 😅
