The option can be detected by looking at the
`prefers-color-scheme` media query.It can be one of the following values:
`light`: User would like to see the page in the light mode`dark`: User would like to see the page in the dark mode`no-preference`: The system doesn't know about the user preferences

js
const isDarkMode = window.matchMedia && window.matchMedia('(prefers-color-scheme: dark)').matches;#See also
