CSS box-shadow Property
The CSS box-shadow property applies shadow to elements. In its simplest use, you only specify the horizontal shadow and the vertical shadow:
      
                    <!DOCTYPE html>	 
<html>
<head>
    <title>CSS Gradient</title>
<style>
div{
    
  width: 300px;
  height: 100px;
  padding: 15px;
  margin-bottom:20px;
}
.box{
    background-color: darkblue;
    box-shadow: 10px 10px grey; /* box shadow length and height*/
}
.box1 {
  background-color: darkblue;
  box-shadow: 10px 10px 5px grey; /* box shadow length, height and blur*/
}
.box2 {
  background-color: darkblue;
  box-shadow: 10px 10px 5px 12px grey; /* box shadow length, height, 
  blur and width of blur*/
}
</style>
</head>
