Is color a new attribute for css3?

Color is not a new property of css3

Color version: CSS1

The color attribute specifies the color of the text.

This property sets the foreground color of an element (in the HTML representation, the color of the element's text); the raster image is not affected by color. This color is also applied to all borders of the element unless overridden by border-color or some other border color attribute.

The easiest way to set the foreground color of an element is to use the color attribute.

Color values can be set in the following ways:

The name of the color, such as red, blue, brown, lightseagreen, etc., is not case-sensitive.

The hexadecimal symbols # RRGGBB and # RGB (for example, # ff0000). "#" is followed by 6 or 3 hexadecimal characters (0-9, Amurf).

RGB, red-green-blue (red-green-blue (RGB)) specifies that the color value is the color of the rgb code, and the function format is rgb (R _ Magi G _ (B)). The value can be an integer or a percentage of 0-255.

RGBA, Red-Green-Blue-Alpha (RGBa) RGBa extends the RGB color model, which includes alpha channels that allow you to set the transparency of a color. A means transparency: 0 = transparent; 1 = opaque.

HSL, hue-saturation-luminance (Hue-saturation-lightness) hue (Hue) represents the angle of the color ring (that is, a ring that represents a rainbow).

Saturation and lightness are expressed as percentages.

100% is full saturation, while 0% is a grayscale.

100% lightness is white, 0% lightness is black, and 50% lightness is "average".

HSLA, Hue-saturation-Luminance-HSLa (HSLa) HSLa extends from the HSL color model and includes alpha channels that specify the transparency of a color. A means transparency: 0 = transparent; 1 = opaque.

Examples are as follows:

Body {color: # 92a8d1;} body {color: rgb;} body {color: rgba);} body {color: hsl (120100%);} body {color: hsla (240100% 50,0.7);}
