Box Shadow in IE7 and IE8: A Comprehensive Guide

Achieving box shadows in IE7 and IE8 can pose challenges, but a viable solution lies in CSS3 PIE. By emulating CSS3 properties in these browsers, CSS3 PIE allows developers to implement box shadows with ease.

CSS Code for Box Shadow

To apply a colored box shadow to a div element, use the following CSS:

.bright {
    position: absolute;
    z-index: 1; 
    box-shadow: 0px -3px 55px 20px #147197;
}

IE-only Solutions

While the CSS code above will work in IE9 and later, it does not support box shadows in IE7 and IE8. To address this, you can use:

ie-css3.htc file: This file provides basic shadow support in IE, but it only creates black shadows.

filter: progid:DXImageTransform.Microsoft.Shadow: This method creates a directional shadow, which may not be ideal for omni-directional shadows.

CSS3 PIE

The most effective solution for box shadows in IE7 and IE8 is CSS3 PIE. This tool emulates the box-shadow property using a combination of HTML and JavaScript. It supports all properties of box-shadow except for the "inset" keyword.

To use CSS3 PIE, download the library and include it in your HTML file:

<script src="PIE.htc"></script>

After including the library, you can apply box shadows as usual. CSS3 PIE will automatically handle the emulation in IE7 and IE8.
