One line of CSS to add basic dark/light mode

You can see it in this codepen:

You can also use the browser developer tools to simulate the different modes to see the difference.

It is great command.
I made Android app, with webview.

To apply dark light, I've changed all colors in my page.

In next update, I will consider using this CSS.
