Html 将滚动添加到 CSS 网格布局中的每一列

Add scroll to each column in CSS Grid Layout

提问by SuddenlyRust

I want separate scroll on each of my columns in my grid layout.

我想在我的网格布局中的每一列上单独滚动。

Currently, I am developing a mobile only web application. I want to use a different grid layout for the portrait and landscape orientations.

目前，我正在开发一个仅限移动的 Web 应用程序。我想为纵向和横向方向使用不同的网格布局。

The portrait orientation is just 1 column and every element is after the other. No problem here.

纵向只有 1 列，每个元素都在另一个之后。这里没问题。

In the landscape orientation I want to use 2 columns. My whole content is displayed on the left side and my navigation moves to the right side. Now I want both parts to have a separate scroll. Is there a way to implement this? And the scroll should stop if the content of the current column ends.

在横向我想使用 2 列。我的全部内容显示在左侧，我的导航移动到右侧。现在我希望这两个部分都有一个单独的滚动。有没有办法实现这个？如果当前列的内容结束，滚动应该停止。

In the left column you have three separate grid items: the header, mainand footerelements.

在左边的列中，您有三个独立的电网项目：header，main和footer元素。

In the right column you have one grid item: the navelement.

在右栏中，您有一个网格项：nav元素。

Adding a scrollbar – vertical or horizontal – to the left column is not feasible because there are three separate elements. You would need to wrap all elements in a container for a single scrollbar to work.

向左列添加垂直或水平滚动条是不可行的，因为存在三个单独的元素。您需要将所有元素包装在一个容器中才能使单个滚动条工作。

Adding a scrollbar – vertical or horizontal – to the right column is pretty easy because there is only one element.

向右列添加垂直或水平滚动条非常容易，因为只有一个元素。

Assuming that you're talking about a vertical scrollbar, here's one way to make it work:

假设您正在谈论垂直滚动条，这是使其工作的一种方法：

body {
  margin: 0;
}

.grid-container {
  display: grid;
  grid-template-columns: 1fr;
  grid-template-rows: 1fr;
  grid-gap: 15px 0;
  height: 100vh;
}

header {
  background-color: green;
  grid-column: 1;
  grid-row: 1
}

main {
  background-color: blue;
  grid-column: 1;
  grid-row: 2;
}

nav {
  background-color: pink;
  grid-column: 1;
  grid-row: 3;
  overflow: auto;
}

footer {
  background-color: teal;
  grid-column: 1;
  grid-row: 4;
}

@media only screen and (orientation: landscape) {
  .grid-container {
    grid-template-columns: 5fr 4fr;
    grid-template-rows: 1fr 1fr 1fr;
  }
  nav {
    grid-column: 2;
    grid-row: 1 / span 3;
  }
  footer {
    grid-row: 3;
  }
}

<div class="grid-container">
  <header>
    <h1>Logo</h1>
  </header>
  <main>
    <h1>content</h1>
  </main>
  <nav>
    <h1>Navigation<br><br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br>nav item<br></h1>

Here is a extended version from my answer on your earlier question, how to get scroll for both header/content/main and nav using flexbox.

这是我对您之前问题的回答的扩展版本，如何使用flexbox.
