The rgba() defines the RGBA color value 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.
Example
Let us now see an example to implement the rgba() function −
<!DOCTYPE html>
<html>
<head>
<style>
#demo1 {background-color: hsla(140, 100%, 50%, 0.8);}
#demo2 {background-color: hsla(130, 100%, 50%, 0.6);}
#demo3 {background-color: hsla(190, 100%, 50%, 0.4);}
#demo4 {background-color: hsla(170, 100%, 50%, 0.3);}
#demo5 {background-color: hsl(150, 100%, 60%);}
#demo6 {
background-color:rgba(108,111,35,0.6);
font-size:30px;
color:yellow;
transform: rotate(45deg);
}
</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">Australian Cricketers</p>
</body>
</html>Output
Example
Let us see another example −
<!DOCTYPE html>
<html>
<head>
<style>
span {
background-color: rgba(100, 150, 50, 0.6);
text-decoration: line-through;
text-decoration-color: blue;
}
.demo2 {
text-decoration: underline;
text-decoration-color: yellow;
}
</style>
</head>
<body>
<h1>Details</h1>
<p class="demo">Examination Center near <span>XYZ College</span> ABC College.</p>
<p class="demo2">Exam begins at 11AM.</p>
</body>
</html>Output
