I started using computers in the era where customisation and user preferences were “allowed” by software companies. Think the Windows 98 or even Windows 7 theme dialog vs modern Windows. I personally reject this seemingly forced binary choice of light and dark.

Because of this for my site I have four themes, light, summer sunshine, forest, and dark. I’ve seen some sites where the theme is an RGB colour picker even.

In regards to the article, that’s a lot of consternation and frustrating statements about toggles and tri-state toggles. A simple button with a dynamic icon works well as soon as you want to cycle through more than two choices.
