我知道这里已经存在这个问题,但是我发现的解决方案不适用于我。我将标头固定在某个位置,但由于另一个问题,最终需要重新设计导航。我试图使标题再次固定在滚动上,但现在它的行为异常。我试着给标题一个高度,并使用“位置:固定”。我还尝试在#nav div中使用此功能,并且两次整个导航和徽标都向下移动到屏幕左侧,并且标题下方的大图像向上移动并接近页面顶部,在导航列表下方。这应该很简单,我浪费了另一个小时来尝试纠正此问题。我可以帮忙吗?

当您应用localhost:8008
时,布局会因为“收缩包装”而改变。
您需要添加更多这样的定位:
position: fixed

这是我的“典型解决方案”,但对我有用:
File "c:\python27\Lib\threading.py", line 384, in notify
raise RuntimeError("cannot notify on un-acquired lock")
这应该确保您的内容不会丢失在标题后面:
header {
height: 200px;
position: fixed;
top: 0;
width: 100%;
background-color: #ffffff;
}
标题背景颜色在那里,因此您的内容不会在其后明显滚动。

尝试一下:
header{
position:fixed;
top:0;
width:100%;
margin:0 auto;
}
