我有一张图片 bg，它使用 CSS 嵌入到页脚上方的 div 中。这个想法是当鼠标向左或向右移动时，图像也随之移动。/body 上面的 Javascript 是导致它工作的原因。它运行良好，但导航链接现在不可点击，内容 div 不透明，您可以通过它们看到 bg 图像。当我删除#bg div 时，一切正常。任何想法如何解决它？ HTML 和 CSS 如下。我从这里的教程中得到了这个:panning .

最佳答案
<div id="bg">标签位于 <div id="body" 中所有其他内容之上 wrapper 。 Z-index 不适用于您的 float 列，因此您必须将您的列包装在另一个 div 中或移动 <div id="bg"> <div id="body" 之外的标签标签。
