有人能帮帮我为什么会这样吗？
我正在为我的大学作业创建网站，当我试图创建固定响应导航栏时，我遇到了这个问题。 当我向下滚动时，身体内容如或将与固定导航栏重叠。
[这是它如何与固定条重叠的示例图片][1]
下面是我的HTML代码:
<html lang= "en">
<head>
<meta charset="utf-8">
<title>Tanat Resort</title>
<meta name="viewport" content="width=device-width, initial-scale= 1">

我想我解决了你的问题。 您所要做的就是将z-index:999（或任何其他高数字）添加到导航栏中。
像这样:
.navbar {
z-index: 999;
}
这允许它位于所有z-index的顶部，而999下面有一个z-index。 您可以在此处了解有关z-index属性的更多信息。 我希望这能帮上忙！
