Another way you can represent colors in CSS is by using rgb
values.
RGB values look like this: rgb(0, 0, 0)
for black and rgb(255, 255, 255)
for white.
Instead of using six hexadecimal digits like you do with hex code, with rbg you specify the brightness of each color with a number between 0 and 255. background-color: rgb(0,0,0);
