Another way you can represent colors in CSS is by using `RGB`

values.

The RGB value for black looks like this:

`rgb(0, 0, 0)`

The RGB value for white looks like this:

`rgb(255, 255, 255)`

Instead of using six hexadecimal digits like you do with hex code, with `RGB`

you specify the brightness of each color with a number between 0 and 255.

If you do the math, the two digits for one color equal 16 times 16, which gives us 256 total values. So `RGB`

, which starts counting from zero, has the exact same number of possible values as hex code.

Let's replace the hex code in our `body`

element's background color with the RGB value for black: `rgb(0, 0, 0)`
