2. Hexadecimal color

Hexadecimal symbols #RRGGBB and #RGB (such as #ff0000). "#" followed by 6 or 3 hexadecimal characters (0-9, A-F).

This is the most commonly used color selection method, for example:

The color value is specified as the color of the rgb code. The function format is rgb(R,G,B), and the value can be an integer or percentage from 0-255.

rgb(255,0,51)
rgb(255, 0, 51)
rgb(100%,0%,20%)
rgb(100%, 0%, 20%)

Extensions: RGBA, Red-Green-Blue-Alpha (RGBa)

RGBA extends the RGB color mode to include an alpha channel, allowing the transparency of a color to be set. a represents transparency: 0=transparent; 1=opaque.

rgba(255,0,0,0.1)    /* 10% 不透明 */  
rgba(255,0,0,0.4)    /* 40% 不透明 */  
rgba(255,0,0,0.7)    /* 70% 不透明 */  
rgba(255,0,0,  1)    /* 不透明，即红色 */

4. HSL, hue-saturation-lightness (Hue-saturation-lightness)

Hue (Hue) represents the color circle (that is, a circle representing a rainbow) ring) at an angle.

Saturation and brightness 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 "normal".

hsl(120,100%,25%)    /* 深绿色 */  
hsl(120,100%,50%)    /* 绿色 */       
hsl(120,100%,75%)    /* 浅绿色 */

Extension: HSLA, Hue-Saturation-Lightness-Alpha (HSLa)

HSLa extends from the HSL color mode and includes the alpha channel, which can specify the transparency of a color. a represents transparency: 0=transparent; 1=opaque.

hsla(240,100%,50%,0.05)   /* 5% 不透明 */   
hsla(240,100%,50%, 0.4)   /* 40% 不透明 */  
hsla(240,100%,50%, 0.7)   /* 70% 不透明 */
