Question

这有点奇怪，因为我最终使用flexbox来对齐sidenav和header中的菜单项，并使用网格来显示/分配{{1} }和nav组件。

我已经尝试过使仅基于网格或基于flexbox的侧边栏（或标题）具有粘性的方法，但是它们根本不起作用。

这是我所拥有的一个例子：

header

CSS：

<div class="grid-container">
    <nav>
        <div class="menu-item">Link</div>
    </nav>
    <div class="header"> Header Content Here </div>
    <main> Main Section. This should be able to scroll while Nav and 
           Header are sticking to the top
    </main>
</div>

Answer 1

像您想做的那样将grid和flexbox属性组合在一起是正确的-您需要添加一些内容才能使它们起作用：

将视口高度添加到网格中，以便使header和sidebar保持粘性。
您可以使用header指定grid-template-rows的高度（请参见下面的代码段）
添加overflow-y: auto以仅强制main溢出。

请参见下面的演示

body  {
  margin: 0;
}

.grid-container {
  display: grid;
  height: 100vh; /* Add total height of the grid */
  grid-template-columns: 200px 1fr; /* sets sidenav width */
  grid-template-rows: 75px 1fr; /* sets header height */
  grid-template-areas: "sidenav header" "sidenav main";
  box-shadow: 5px 10px !important;
}

nav {
  grid-area: sidenav;
  box-shadow: 0 -1px 12px 2px whitesmoke;
  background-color: white;
  z-index: 100;
  border: 1px solid;
}

.header {
  grid-area: header;
  background-color: #f8f9ff;
  display: flex; /* flexbox to center items */
  align-items: center;
  justify-content: space-between;
  padding: 0px 16px;
  border: 1px solid;
}

main {
  grid-area: main;
  background-color: #f8f9ff;
  border: 1px solid;
  overflow-y: auto; /* add scrolling */
}

<div class="grid-container">
  <nav>
    <div class="menu-item">Link</div>
  </nav>
  <div class="header"> Header Content Here </div>
  <main> Main Section. This should be able to scroll while Nav and Header are sticking to the top<br/> Lorel ipsum some text here <br/> Lorel ipsum some text here <br/> Lorel ipsum some text here <br/> Lorel ipsum some text here <br/> Lorel ipsum some text here

首先将display: grid添加到容器中，然后从display: none元素中删除nav。然后将overflow: auto添加到main元素以启用滚动功能。

.grid-container {
  height: 100vh;
  display: grid;
  grid-template-columns: 200px 1fr;
  grid-template-areas: "sidenav header"
                       "sidenav main";
}

nav {
  grid-area: sidenav;
  background-color: aqua;
}

header {
  grid-area: header;
  height: 50px;
  background-color: orange;
}

main {
  grid-area: main;
  overflow: auto;
  background-color: #f8f9ff;
}

body {
  margin: 0;
}

<div class="grid-container">
  <nav>nav section</nav>
  <header>header section</header>
  <main>Main Section. This should be able to scroll while Nav and Header are sticking to the top<br><br>Main Section. This should be able to scroll while Nav and Header are sticking to the top<br><br>Main Section. This should be able to scroll while Nav and

  </main>
</div>

将元素固定到视口顶部
