jQuery图像滑块不显示IE7上的内容

时间：2012-12-02 00:35:47

标签： jquery html css

我有一个交换图像和文本的jQuery滑块，我遇到的问题是在IE7及以下版本中我无法将幻灯片内容显示在图像上方。

示例（IE7）：

ie7

（铬） chrome

这是网站：http://new.dpwebdev.co.uk/business-sites/explore-d-and-d/index.php

我尝试更改图片和文字z-index，但这不会影响IE7。有没有办法解决这个问题？

我也注意到箭头也丢失了。

答案 0 :(得分：1)

修正了!!通过更改包装器的CSS：

#home #content #top-slide .wrapper {
    position:relative;
    z-index:9998;
}

当我改变箭头的容器时也知道了：

#home #content #top-slide .arrows {
    width:1100px;
    margin:0 auto;
    height:300px;
    position:relative;
    z-index:9998;
}
