I'm working on a website that features a "day" mode and a "night" mode that the user can toggle between. The day mode will have a light background with dark text, the night mode will have a dark background with light text.
The current idea is to have this controlled by an icons of a sun and a moon. When the user clicks the icon, it switches to the other mode.
Which icon should show when in day mode? The current active mode (sun) or the mode the user will switch to if clicked (moon)?
There are related answers, but those deal more with audio player controls. I would follow the advice there, but I've seen this sort of toggle handled the opposite of the advice given in those posts. Here's one: http://blog.mengto.com
