javascript - 当用jQuery动画框时，为什么CSS3框阴影会分离？

我有一个带有框阴影的图像，但是当我对其进行动画处理时，框阴影似乎具有自己的生命，如下所示：

在chrome，firefox和IE中，它的发生方式相同。
我很困惑，更重要的是不知如何修复它，看起来很漂亮。

感谢您为解决此问题或发生问题的任何想法或答案。

CSS：

#sliderPane{
    height: 200px;
    position: relative;
    overflow: hidden;
    background-image: url('sliderBG.png');
    background-size: 100% 100%;
    padding: 20px 0;
}

.slider{
    position: absolute;
    opacity: 0;
    top: -300px;
    box-shadow: 2px 2px 10px 5px rgba(0,0,0,.4);
}

#numSliders{
    visibility: hidden;
}
