RGB colors in CSS use

Colors in CSS web designers can define three ways, with color names, hex and RGB codes. The latter is the most intuitive, because you do not have to learn the value of letters, such as Hex.

p
 {
 color:rgb(0,0,255);
 }

That’s all. This is the color of your blue letters.

p
 {
 background:rgb(0,0,255); color:rgb(255,255,255);
 }


This is the background color of your blue point and white letters.

Play it and you come out behind itself.
