The
rgba()color notation allows you to specify the red, green, blue and alpha values for a color respectively. That means 221 red, 221 green, 221 blue and 0.6 (60%) alpha.The RGB values have a range of 0 to 255; this is the standard range for the RGB color model and notation (this is explained in the preceding section for the
rgb()notation). The higher the value for a color component, the more that color component will be blended into the resulting color.The alpha value has a range of 0 to 1, with decimal values. It is what determines the opacity (or transparency) of the color. The higher the value, the more opaque the resulting color will be.
