Add a blur effect to the shadow with CSS
The CSS box-shadow property allows you to add shadow effects around an element. When you specify a blur radius value, it creates a soft, blurred shadow instead of a sharp one.
Syntax
selector {
box-shadow: offset-x offset-y blur-radius color;
}
Parameters
| Parameter | Description |
|---|---|
offset-x |
Horizontal shadow offset (required) |
offset-y |
Vertical shadow offset (required) |
blur-radius |
Amount of blur applied to shadow (optional) |
color |
Shadow color (optional) |
Example
The following example demonstrates how to add a blur effect to a shadow −
<!DOCTYPE html>
<html>
<head>
<style>
h2 {
box-shadow: 10px 10px 7px green;
height: 50px;
background-color: yellow;
margin: 20px;
display: flex;
align-items: center;
padding-left: 15px;
}
</style>
</head>
<body>
<h2>Heading Two</h2>
<p>Above heading has a blurred green shadow.</p>
</body>
</html>
A yellow heading box appears with a green blurred shadow offset 10px right and 10px down, with a 7px blur radius creating a soft shadow effect.
Conclusion
The box-shadow property with a blur radius creates smooth, professional shadow effects. The larger the blur radius value, the softer and more diffused the shadow appears.
