CSS Grid 在 Firefox 和 Safari 中不起作用

Why is percentage height not working on my div? [duplicate]

Chrome / Safari not filling 100% height of flex parent

我正在构建一种后网格 slider ，它将在 CSS 网格中显示 4 个框。我建立了一切，它按预期工作，但它在 Firefox 中不起作用。

Firefox 和 Safari 都存在显示网格高度的问题。它们导致 0 或 1px。为了解决这个问题，我使用了 display:flex 和 flex-flow 设置为换行。这在 Safari 中有效，但在 Firefox 中无效。当我从容器中删除 flex 时，它在 Firefox 中有效，但在 Safari 中无效。

Edge 和 Chrome 两种方式都很好。我迷失在寻找解决方案并尝试解决它，但结果仍然相同。

我正在使用 padding-top 和 position absolute 来“按比例”响应网格及其元素。

谢谢您的回复。

我突然发现了一个解决方案。我从容器和包装器中删除了 flexbox。我添加了 height:0;包装。它似乎在所有浏览器中都按预期工作。

我已经更新了 codepen 演示。

.post-grid-slider {
  height:100%;
  padding: 0 15px;
}

.post-grid-wrapper {
  position: relative;
  width:100%;
  height: 0;
  padding-top: 25%;
}

.post-grid {
  position: absolute;
  top: 0;
  right: 0;

  grid-template-columns: auto;
  -ms-grid-rows: 50% 50%;
  grid-template-rows: 50% 50%;
