CSS grid-template-columns 的行为方式与我不同答案

【问题标题】：CSS grid-template-columns not behaving the way I it toCSS grid-template-columns 的行为方式与我不同
【发布时间】：2018-02-06 04:56:53
【问题描述】：

我是 CSS 网格的新手，这是我的第一次尝试。

在下面的代码中有一个带有网格包装器类的 div 容器。它包含两个子 div，类名为 grid-item。在 CSS 中，它们被称为 grid-item:nth-child(1) 和 grid-item:nth-child(2)。在 grid-wrapper 中，grid-template-areas 正确放置了 grid-item:nth-child(1) 和 grid-item:nth-child(2)。

grid-item:nth-child(2) 有自己的子项，但我无法让它们正确排列。

我确实有一个 FSFiddle 项目。

有人可以启发我吗？提前致谢。

    grid-template-areas:

      ". tabs tabs tabs tabs tabs tabs .";
}

.grid-item:nth-child(1) {

【解决方案1】：

在内部网格项目中使用display:grid...并使用grid-auto-flow: column 将它们按列对齐...使用justify-content: center 将项目水平居中对齐..

您还为 grid-template-columns. 使用了错误的值。我看到您不需要这个，所以删除它

将 .grid-item:nth-child(2)>div 更改为 .grid-item:nth-child(2) div

将 .grid-item:nth-child(2)>div 更改为 .grid-item:nth-child(2) div 不起作用，但下面的下一个答案可以。非常感谢您的快速回答。
