CSS Grid在Firefox和Safari中无法正常工作。

Question

我正在构建一种帖子网格滑块，它会在CSS网格中显示4个框。我已经构建了所有内容，并且按预期工作，但在Firefox中无法正常工作。

Firefox和Safari都存在显示网格高度的问题。它们的结果为0或1像素。为了解决这个问题，我使用了display:flex并将flex-flow设置为row wrap。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两种方式都可以正常工作。我正在寻找解决方案并尝试解决它，但结果仍然相同。

我使用padding-top和position absolute来实现'成比例'响应式网格及其项目。

谢谢您的回复。 https://codepen.io/Mariopa/pen/ELjqYr

我突然找到了一个解决方案。我将容器和包装器中的flexbox删除，并向包装器添加了height：0；。这似乎在所有浏览器中都按预期工作。

我已更新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;
  left: 0;
  bottom: 0;
  display: -ms-grid;
  display: grid;
  -ms-grid-columns: auto;
  grid-template-columns: auto;
  -ms-grid-rows: 50% 50%;
  grid-template-rows: 50% 50%;
  grid-column-gap: 0.0625rem;
  grid-row-gap: 0.0625rem;
  width: 100%;
  height: 100%;
}
.post-grid__item {
  position: relative;
  overflow: hidden;
}

.post-grid__item:nth-child(1) {
  -ms-grid-column: 1;
