CSS3 Box-Shadow Property
The CSS3 box-shadow property applies shadow to elements. In its simplest style form {box-shadow: 10px 10px;}, you only specify the horizontal shadow and the vertical shadow:
div {
width: 300px;
height: 150px;
padding: 15px;
margin-bottom: 30px;
background-color: yellow;
box-shadow: 10px 10px;
}
The style of {box-shadow: 10px 10px grey;} will add a color to the shadow:
div {
width: 300px;
height: 150px;
padding: 15px;
margin-bottom: 30px;
background-color: yellow;
box-shadow: 10px 10px grey;
}
Changing the style to {box-shadow: 10px 10px 5px grey;}, we've inserted another value before the color to create a blur effect to the shadow:
div {
width: 300px;
height: 150px;
padding: 15px;
margin-bottom: 30px;
background-color: yellow;
box-shadow: 10px 10px 5px grey;
}
