我目前正在开发一个带有粘性导航的页面，但我的主要问题是我使用了多个以图像作为背景的部分，而且导航当然是透明的。真正重要的是 Logo 在导航上方，所以我真的必须使用 display: sticky;(或 .sticky-top)。如何让它在每个部分都可见？
html,
body {
width: 100% !important;
}
body {
background: grey !important;
}
/*Header*/
.logo {
display: inline-block;
padding: 1rem 0 .5rem 0 !important;
}
/* NavBar */
nav {
font-size: 13pt;
font-family: 'Cinzel', sans-serif;
padding: .3rem 0 .3rem 0 !important;
text-transform: capitalize;
}
.nav-link {
color: #fff !important;
margin: 0 25% 0 25%;
}
.nav-link:hover {
font-style: underline;
}
section {
height: 100vh;
min-height: 900px;
background-position: center;
background-repeat: no-repeat;
background-size: cover;
}
.Text {
margin-top: 20%;
}<html>

解决方法:
取出导航栏和 Logo 并将它们放在所有部分的上方。 Logo 和导航栏一起高 256 像素。
所以，应用 margin-top: -256px; padding-top: 256px; 到第一部分，你就完成了!
margin-top: -256px; 将第一部分向上移动 256px 并且 padding-top: 256px; 为其提供 265px 顶部填充。这让整个事情看起来和以前一样，但现在你的导航栏和标志标题是独立于这些部分的。这就是它起作用的原因。
