标签: html css z-index

我尝试将我的徽标(我在CSS中制作)放在导航栏上方。徽标具有负z指数。我试着解决它。但我仍然不知道如何解决它。当我加载代码时,它将徽标放在导航栏上。任何人都可以帮我将徽标放在导航上方吗?

在.neon上使用position:absolute将其从DOM的流中取出并将其置于其他元素的上方(在其上方)。没有它,您可以实现所需的居中。

为了解决您的问题,我做了以下事情:

  • 将.neon显示更改为&#39; inline-block&#39;
  • 将.neon位置更改为&#39; relative&#39;
  • 更改.neon:在内容发布后&#39;&#39; (空)
  • 从.neon中移除了z-index:在
  • 之后
  • 将.neon:之前的z-index更改为-1
