CSS Box Shadow

The CSS box-shadow property can be used to give block elements a drop shadow or an inner shadow. Let’s take a close look at this CSS property.

Examples:

There will be few examples where we discuss on box shadow property.

Adding box shadow to a div 📦
```
<div class='one'>One</div>
```
```
.one {
    /* offset-x | offset-y */
    box-shadow: 5px 5px;
}**
```
In the above snippet, You have not given any drop shadow color, then by default the color will be black.

Adding colour to drop-shadow 🎨

<div class='two'>Two</div>

.two {
    /* offset-x | offset-y | color */
    box-shadow: 5px 5px red;
}

Adding blur-radius to the drop-shadow 💧

<div class='three'>Three</div>

.three {
     /* offset-x | offset-y | blur-radius | color */
     box-shadow: 5px 5px 20px red;
}

Adding spread-radius to the drop shadow ☄️

<div class='four'>Four</div>

.four {
    /* offset-x | offset-y | blur-radius | spread-raidus | color */
    box-shadow: 0 0 10px 5px #ff000066;
}

Adding inset to the div for drop shadow 💧
```
<div class='five'>Five</div>
```
```
.five {
    /* inset || offset-x | offset-y | blur-radius | spread-raidus | color */
    box-shadow: inset 0px 0px 13px 4px pink;
}
```
If you don't explicitly state a color value for your box shadow — the shadow’s color will be equal to the color value of the HTML element the box-shadow property is being applied to. For instance, if you have a div that has the color of red, the box shadow’s color will also be red:
```
<div class='six'>Six</div>
```
```
.six {
    color: red;
    box-shadow: 0px 0px 3px 2px;
}
```
If you want a different shadow color, then you’ll need to specify it in the box-shadow property value declaration. Below you can see that even though the foreground color of the div is still red, the box shadow color is blue.
```
<div class='seven'>Seven</div>
```
```
.seven {
    color: red;
    box-shadow: 0px 0px 3px 2px blue;
}
```

This is where you can get really creative with this CSS property:

You can apply more than one box shadow on an element.

Syntax:

box-shadow: [box shadow properties 1], [box shadow properties 2], [box shadow properties n];

In other words, you can have multiple box shadows by separating each property value group with commas (,).

In the below example, there are two box shadows.

<div class='eight'>Eight</div>

.eight {
    box-shadow: 5px -7px 2px 2px blue, -5px 5px 5px 5px pink;
}
