**Usage**

This method changes the `CSS media type` through the `media` argument, and/or the `'prefers-colors-scheme'` media feature, using the `colorScheme` argument.

def emulate_media(colorScheme: nil, forcedColors: nil, media: nil, reducedMotion: nil)
  wrap_impl(@impl.emulate_media(colorScheme: unwrap_impl(colorScheme), forcedColors: unwrap_impl(forcedColors), media: unwrap_impl(media), reducedMotion: unwrap_impl(reducedMotion)))
end
