- HSL colors
- HSLA colors
- Opacity
RGBA stands for Red Green Blue Alpha.It is an extension of CSS2,Alpha specifies the opacity of a color and parameter number is a numerical between 0.0 to 1.0. A Sample syntax of RGBA as shown below −
#d1 {background-color: rgba(255, 0, 0, 0.5);} #d2 {background-color: rgba(0, 255, 0, 0.5);} #d3 {background-color: rgba(0, 0, 255, 0.5);}
HSL stands for hue, saturation, lightness.Here Huge is a degree on the color wheel, saturation and lightness are percentage values between 0 to 100%. A Sample syntax of HSL as shown below −
#g1 {background-color: hsl(120, 100%, 50%);} #g2 {background-color: hsl(120, 100%, 75%);} #g3 {background-color: hsl(120, 100%, 25%);}
HSLA stands for hue, saturation, lightness and alpha. Alpha value specifies the opacity as shown RGBA. A Sample syntax of HSLA as shown below −
#g1 {background-color: hsla(120, 100%, 50%, 0.3);} #g2 {background-color: hsla(120, 100%, 75%, 0.3);} #g3 {background-color: hsla(120, 100%, 25%, 0.3);}
opacity is a thinner paints need black added to increase opacity. A sample syntax of opacity is as shown below −
#g1 {background-color:rgb(255,0,0);opacity:0.6;} #g2 {background-color:rgb(0,255,0);opacity:0.6;} #g3 {background-color:rgb(0,0,255);opacity:0.6;}
The following example shows rgba color property.
<html> <head> <style> #p1 {background-color:rgba(255,0,0,0.3);} #p2 {background-color:rgba(0,255,0,0.3);} #p3 {background-color:rgba(0,0,255,0.3);} </style> </head> <body> <p>RGBA colors:</p> <p id = "p1">Red</p> <p id = "p2">Green</p> <p id = "p3">Blue</p> </body> </html>
