html - 如何使用 CSS 网格正确制作页面布局？

问题描述

下面是我尝试使用网格进行页面布局。但是，滚动条位于标题下方。

发生这种情况是因为我添加overflow:auto了部分标签。由于我对使用网格布局不够熟悉，我不确定如何使用网格正确实现页面布局。有没有解决的办法？有没有更好的解决方案来实现我想要做的事情？

body {
            font-size: 24px;
            height: 100vh;
            margin: 0;
            display: grid;
            grid-template-columns: minmax(150px, 200px) auto;
            grid-template-rows:  54px auto;
            grid-template-areas: "header header"
                                "nav    section";
        }

        header {
            grid-area: header;
            background: red;
        }

        nav {

  min-height: 100vh;
  margin: 0;
  display: grid;
  grid-template-columns: minmax(150px, 200px) auto;
}

header {
  background: red;
  position: fixed;
  height: var(--header-height);
  width: 100%;
}

nav {
  grid-column: 1;
  display:flex;
  flex-direction: column;
  justify-content: space-between;
  background: blue;
  margin-top: var(--header-height);
}
section {
