我在将固定导航置于页面顶部时遇到问题。我试过 position: fixed with top: 0 和 width: 100%，但是放置在导航栏底部的 Bootstrap 的图像是重叠的。这是我的 HTML 和 CSS 的全部代码。几个小时以来一直试图通过资源找到这个问题，但我仍然不知道问题是什么..

}
.top {
margin: auto;

overflow: hidden;
background-color: #0a0908;
width: 100%;
top: 0;
position: fixed;
display: block;
/*position: -webkit-sticky;
position: sticky;*/

最佳答案
尝试将 z-index:100 添加到导航栏，使其位于所有其他元素的前面。
此外，如果您将 z-index 添加到其他元素，该数字应低于 100 或您为 z-index
关于html - 固定导航栏即使使用位置 : fixed in css 也不起作用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/64826660/
