Today I scratched my itch of implementing a dark mode toggle without JacaScript. The implementations I saw typically revolved about adding a 'dark' class to body via JS and then controlling it with JS handlers.
Thanks to `:has()` selector [0], that passed 90% browser compatibility [1], it is possible to avoid JS.
My implementation uses CSS variables combined with a checkbox, `:checked`, and `:has()`. It is simple, yet supports color scheme preference and updates toggle's label based on active mode.
