无法获得网格区域以填充垂直空间

Question

我试图使用css-网格来创建3个区域，2个固定的高度和底部的一个来填补可用的空间按钮网格，也适应可用的空间。这些按钮将水平调整，而不是垂直调整。你能看到我在做什么蠢事来阻止它发挥作用吗？

Answer 1

网格容器设置为<div class="panel">。

.panel {
    display: grid;
    grid-template-columns: 1fr;
    grid-template-rows: 80px 80px 1fr;
}

但你在问题中提到的三个方面：

• .top-panel
• .grid-position-2-1
• .grid-position-3-1

不是网格容器的子级。他们是.panel的孙子。

因此，它们不是网格项。

网格格式上下文的范围仅限于父-子关系.

这意味着网格容器始终是父容器，网格项始终是子容器。网格属性仅在此关系中工作。

如规范所述：

6.网格项目 网格容器的每个流中子元素都成为网格项。

子网格容器之外的网格容器的后代不是网格项，也不会接受网格属性。而且，正如上面的规范语言所暗示的那样，没有人流的孩子 (即绝对定位)也不是网格项。

底线:要使网格属性在子属性上工作，始终需要将display: grid或display: inline-grid应用于父级。
