How to create a box shadow effect in IE7 and IE8?

Box Shadow in IE7 and IE8

CSS box shadows are a powerful way to add depth and dimension to elements on a web page. However, these shadows are not supported in IE7 and IE8. To achieve the desired effect, you can use a combination of HTML, CSS, and JavaScript.

CSS Solution

One option is to use the CSS3 PIE library, which allows you to emulate CSS3 properties in older versions of IE. PIE supports box-shadow (with the exception of the inset keyword), so you can use it to apply box shadows to elements in IE7 and IE8. Below is the updated CSS that you can use:

.bright{
    position: absolute;
    z-index: 1; 
    -moz-box-shadow: 0px -3px 55px 20px #147197;
    box-shadow: 0px -3px 55px 20px #147197;
    -webkit-box-shadow: 0px -3px 55px 20px #147197;
    behavior: url(ie-css3.htc);
}

Note that you will need to download the ie-css3.htc file and include it in your web page.

JavaScript Solution

Another option is to use JavaScript to create a box shadow effect. You can use the JavaScript library BoxShadows.js, which adds support for box shadows to IE7 and IE8. Here is how you can use it:

<div class="bright"></div>

$(".bright").boxShadow({
    x: 0,
    y: -3,
    blur: 55,
    color: "#147197"
});

IE Browser Compatibility

It is important to note that IE7 does not support modern features such as CSS3 box shadows, so you will need to use a polyfill or JavaScript solution to achieve this effect. IE8 supports some CSS3 features, but not all of them. Therefore, you should use a feature detection script to determine which features are supported and use the appropriate fallback methods accordingly.
