In this tutorial we are going to learn how to use the CSS box shadow property to create different effects with just CSS. Below is an image created in photoshop of different box shadows effects. These used to be the only way of creating this effect but thanks to CSS3 we can now do all this with just CSS. View Demo page to see what we are going to create CSS Box Shadow Effects Demo

CSS Box Shadow

We are going to be using the CSS box shadow property which is one my favourite CSS properties which you will see in this tutorial how easy you can use it. The box-shadow property allows you to easily create multiple drop shadows on box elements by specifying values for colour, size, blur and offset. The box-shadow property accepts 2-6 options, the required options are horizontal offset and vertical offset, the two optional options are spread distance and colour.

box-shadow: inset horizontal vertical blur spread colour;

Examples

box-shadow: 10px 10px;
box-shadow: 10px 10px 5px #888;
box-shadow: inset 2px 2px 2px 2px black;
box-shadow: 10px 10px #888, -10px -10px #f4f4f4, 0px 0px 5px 5px #cc6600;

Browser Support

All of the major newest browsers support box-shadow property. - Internet Explorer 9.0 and higher

• Firefox 3.5 and higher
• Chrome 1 and higher
• Safari 3 and higher

• Opera 10.5 and higher

  With many new CSS3 properties you need to prefix the property with browser specific tags. For firefox you need to use -moz-, for chrome/safari you need to use -webkit. The box-shadow property is no different. For Firefox 3.5 you need to prefix with -moz-boz-shadow, but for Firefox 4.0 and higher you don't need to use the prefix anymore. For Chrome/safari you still need to use the -webkit-box-shadow. For opera you don't need to prefix the property and can just use box-shadow. ## CSS Box Shadow Effect 1

  This will create a standard box shadow effect with the shadow moved into the element to create a raised box look. ### The HTML

<div class="box effect1">
