Dark mode

[janbarasek]

Detect:

if (window.matchMedia && window.matchMedia('(prefers-color-scheme: dark)').matches) {
    // dark mode
}

To watch for changes:

window.matchMedia('(prefers-color-scheme: dark)').addEventListener('change', e => {
    const newColorScheme = e.matches ? "dark" : "light";
});
