Defining Colors in CSS3

CSS Web Development Front End Technology

To define colors in CSS3, use RGB, RGBA, HSL and HSLA. With that, you can use the color value and hexadecimal value can also be used for defining colors −

The CSS3 RGBA color value is for Red, Green, Blue and Alpha. The alpha is the color opacity i.e. a number between 0.0 and 1.0. Here, 1.0 would be for full opaque. Here, we can see the difference in opacity created with the Alpha parameter in RGBA −

Example

Let us now see an example for RGBA color values −

Live Demo

<!DOCTYPE html>
<html>
<head>
<style>
#demo1 {background-color:rgba(108,111,35,0.6);}
#demo2 {background-color:rgba(108,111,35,0.5);}
#demo3 {background-color:rgba(108,111,35,0.4);}
#demo4 {background-color:rgba(108,111,35,0.3);}
#demo5 {background-color:rgba(108,111,35,0.2);}
#demo6 {background-color:rgba(108,111,35,0.1);}
</style>
</head>
<body>
<h1>Cricketers</h1>
<p id="demo1">David Warner</p>
<p id="demo2">Steve Smith</p>
<p id="demo3">Mark Waugh</p>
<p id="demo4">Steve Waugh</p>
<p id="demo5">David Johnson</p>
<p id="demo6">Andy Bichel</p>
</body>
</html>

Output

The CSS3 HSL is for Hue, Saturation and Lightness when color is set for elements. Hue value is from 0 to 260, wherein 0 or 360 is for red, 240 for bluw, whereas 120 for green. Saturation and Lightness is a percentage value.

Example

Let us now see an example for HSL color values −

Live Demo

<!DOCTYPE html>
<html>
<head>
<style>
#demo1 {background-color: hsl(150, 100%, 50%);}
#demo2 {background-color: hsl(150, 100%, 50%);}
#demo3 {background-color: hsl(140, 100%, 40%);}
#demo4 {background-color: hsl(120, 100%, 40%);}
#demo5 {background-color: hsl(120, 100%, 30%);}
#demo6 {background-color:rgba(108,111,35,0.6);}
</style>
</head>
<body>
<h1>Cricketers</h1>
<p id="demo1">David Warner</p>
<p id="demo2">Steve Smith</p>
<p id="demo3">Mark Waugh</p>
<p id="demo4">Steve Waugh</p>
<p id="demo5">David Johnson</p>
<p id="demo6">Andy Bichel</p>
</body>
</html>

Output

The HSLA color value is for Hue, Saturation, Lightness and Alpha. The alpha is the color opacity i.e. a number between 0.0 and 1.0. Here, 0.0 is for fiully transparent, whereas 1.0 would be for full opaque.

Example

Let us now see an example −

#demo3 {background-color: hsla(190, 100%, 50%, 0.4);}
#demo4 {background-color: hsla(170, 100%, 50%, 0.3);}
