CSS Transparency Using RGBA
Use the RGBA() values for CSS transparency. Set the alpha channel parameter to specify the opacity for color −
.transparent {
background-color: rgba(0, 0, 255, 0.582);
}
RGBA color value includes the rgba(red, green, blue, alpha). Here, the alpha is to be set for transparency i.e. −
0.0: fully transparent
1.0: fully opaque
Transparency With RGBA
The following is the code for implementing CSS transparency using RGBA. Here, we have set the alpha parameter to a value 0.582 for transparency −
Example
<!DOCTYPE html>
<html>
<head>
<style>
body {
font-family: "Segoe UI", Tahoma, Geneva, Verdana, sans-serif;
}
div {
width: 200px;
height: 200px;
background-color: rgb(0, 0, 255);
color: white;
display: inline-block;
}
.transparent {
background-color: rgba(0, 0, 255, 0.582);
}
</style>
</head>
<body>

Full Transparency With RGBA
The following is the code for implementing CSS transparency using RGBA. Here, we have set the alpha parameter to a value 0.0 for full transparency −
Example
<!DOCTYPE html>
<html>
<head>
<style>
body {
font-family: "Segoe UI", Tahoma, Geneva, Verdana, sans-serif;
}
div {
width: 200px;
height: 200px;
background-color: rgb(0, 0, 255);
color: white;
display: inline-block;
}
.transparent {
background-color: rgba(0, 0, 255, 0.0);
}
</style>

Fully Opaque With RGBA
The following is the code for implementing CSS transparency using RGBA. Here, we have set the alpha parameter to a value 1.0 for fully opaque −
Example
<!DOCTYPE html>

<head>
<style>
body {

}
div {
width: 200px;

background-color: rgb(0, 0, 255);
color: white;
display: inline-block;
}
.transparent {
background-color: rgba(0, 0, 255, 1.0);
}
