CSS Box Shadow

CSS Box Shadow is a powerful styling property that adds depth and dimension to elements on a webpage. It enables designers to create visually appealing effects, making elements stand out by casting a shadow behind them. This simple yet effective feature can significantly enhance the overall look and feel of a website.

Basic Syntax

The box-shadow property allows you to add a shadow effect to an element. Its basic syntax is as follows:

<div class="shadow-example">
  <!-- Your content here -->
</div>

<style>
  .shadow-example {
    width: 200px;
    height: 200px;
    background-color: #f0f0f0;
    box-shadow: 5px 5px 10px rgba(0, 0, 0, 0.3);
  }
</style>

In the above example, the box-shadow property is applied to a <div> element with the class shadow-example. This property takes several values:

• Horizontal offset: Specifies the horizontal distance of the shadow from the element. (Positive values move the shadow to the right, negative values to the left.)
• Vertical offset: Specifies the vertical distance of the shadow from the element. (Positive values move the shadow downwards, negative values upwards.)
• Blur radius: Indicates the amount of blur applied to the shadow. Higher values create a more diffused shadow.
• Spread radius: Optional parameter that extends or contracts the shadow. A positive value increases the size of the shadow, while a negative value decreases it.
• Color: Defines the color of the shadow. This can be specified using color names, hexadecimal, RGB, or RGBA values.

Examples

Basic Shadow

Let’s apply a basic shadow to a div element:

<div class="basic-shadow"></div>

<style>
  .basic-shadow {
    width: 150px;
    height: 150px;
    background-color: #ddd;
    box-shadow: 3px 3px 5px rgba(0, 0, 0, 0.3);
  }
</style>

Multiple Shadows

You can also add multiple shadows to an element:

<div class="multiple-shadows"></div>

<style>
  .multiple-shadows {
    width: 200px;
    height: 100px;
    background-color: #b7eaff;
    box-shadow: 0 0 5px #000, 0 0 10px #00bcd4, 0 0 15px #03a9f4;
  }
</style>

Inset Shadow

The inset keyword creates an inner shadow effect:

<div class="inset-shadow"></div>

<style>
  .inset-shadow {
    width: 150px;
    height: 75px;
    background-color: #f0f0f0;
    box-shadow: inset 3px 3px 5px rgba(0, 0, 0, 0.3);
  }
</style>
