Syntax:

Rgb (rmae gpene b)

R: sets the red value, which can be set as a positive integer or percentage

G: set the green value, which can be set as a positive integer or percentage

B: sets the blue value, which can be set as a positive integer or percentage.

Description: each parameter (r, g, and b) in rgb () defines the intensity of different colors and can be a positive integer between 0 and 255, or a percentage value (from 0 to 100%).

Let's use a simple code example to see how rgb () sets the color.

Div {

Width:350px

Height:200px

Background-color:rgb (0d0j0pl 0)

Color:rgb (255255255)

Border:1pxsolidrgb (255, 010, 0)

Padding:10px

}

This is a piece of test code

Set the background color of the box to black [rgb (0memo 0jin0)]

Set the color of font text to white [rgb (255255255])

The border color is red [rgb (255pm 0pc0)]

In the above example, we set the background color, font text color, and border color of the box by setting different rgb () color values for background-color,color,border.

We should pay attention to how to write the color value of rgb (). In the following code example, some of the values of the rgb () function are right and some are wrong. Pay attention to the distinction:

/ * use the value method of positive integer * /

Rgb (255j0pl 51)

Rgb (255jue 51.2) / * incorrectly written, cannot be a floating point number, it must be a positive integer * /

/ * use the value method of% * /

Rgb (100%, 0%, 20%)

Rgb (100% zero zero 20%) / * incorrect writing, cannot mix integer and percentage values * /
