【问题描述】：
我正在构建一种后网格滑块，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 都适用于这两种方式。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”响应网格及其项目。
