固定图像重叠另一个div

Question

我在页面上有不同的部分。然后我在这些部分下修复了一个图像。然后我的上一节有很大的余量，所以当用户向下滚动时，它们会看到图像并且会给它带来3d效果。我的问题是我的#vanishing-text-container div没有显示在图像上。我不确定为什么因为我添加了z-index的1，它高于图像。

有没有人知道为什么我的#vanishing-text-container div没有显示在图片上？

Answer 1

你在＃消失文本容器上缺少某种位置。如果没有职位，z-index将无效。

消失文本容器{position：relative; }

这应该解决它。
