• 2. Hexadecimal color

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

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 */

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 */ hsla(240,100%,50%, 1) /* 完全不透明 */
