箱子阴影在IE7和IE8

我想在IE7和IE8中实现框阴影。
我试过一切没有成功。这里是我使用的CSS应用彩色阴影到div：

I want to implement box shadows in IE7 and IE8. I have tried everything without succeeding. Here is the css that I am using to apply colored shadow to a div:

.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);
}

这个ie-css3.htc文件是IE阴影问题的解决方案。但它只给出黑色阴影，而不是颜色阴影。我试过：

This ie-css3.htc file is a solution to IE shadow problems. But it only gives black shadows, not colour shadows. I tried:

filter: progid:DXImageTransform.Microsoft.Shadow(color='#969696', Direction=100, Strength=13);

但它创建了一个定向阴影，我想要一个全方位阴影。也尝试了模糊过滤器，但它需要有额外的div在我目前的情况下是不可取的。对此问题有任何专家意见？

But it creates a directional shadow, and I want an omni-directional shadow. Also tried blur filter but it needs to have additional divs which is unadvisable in my current case. Any expert opinion on this problem ?
