我真的被 HTML5 的一个小问题困扰了。
我只是想定位一个固定元素，我有一个 jpg 作为标题，在下面我有一个名为 menu 的 div，其中包含导航。
我一直在尝试通过 jss 和许多 css 规则使这个 div 菜单固定，因为当我向下滚动时，我希望该 div 保持在顶部位置，而页面的其余部分滚动。
这是代码，谢谢大家！
//Edit1：我尝试过使用标题CSS，但这不是重点，我试图覆盖菜单，甚至标题，我找到了一个示例，但我无法成功编辑代码：

需要添加，不添加请注意z-index那么内容将与您的代码重叠标题。
header {
position: fixed;
top: 0;
left: 0;
z-index: 999;
}
