Bootstrap flex 列在 Firefox 中无法正常工作

Question

在 Chrome 中我有 2x2 table -

在rows 中都有col-md-6 和col-md-6

但在 Firefox 中，我有 4x1 table，所有 col-md-6 块显示在一行中。

是否可以在 Firefox 中获取 2x2 表格？

我正在使用这个 sn-p：

html,
body {
  height: 100%;
}
.row-flex,
.row-flex > div[class*='col-'] {
  display: -webkit-box;
  display: -moz-box;
  display: -ms-flexbox;
  display: -webkit-flex;
  display: flex;
  flex: 1 1 auto;
}
.row-flex-wrap {
  -webkit-flex-flow: row wrap;
  align-content: flex-start;
  flex: 0;
}
.row-flex > div[class*='col-'],
.container-flex > div[class*='col-'] {
  margin: -.2px;
  /* hack adjust for wrapping */
}
.container-flex > div[class*='col-'] div,
.row-flex > div[class*='col-'] div {
  width: 100%;
}
.flex-col {
  display: flex;
  display: -webkit-flex;
  flex: 1 100%;
  flex-flow: column nowrap;
}
.flex-grow {
  display: flex;
  -webkit-flex: 2;
  flex: 2;
}

Answer 1

您需要将flex-wrap:wrap 添加到.row-flex,.row-flex > div[class*='col-']，这样col-md-6 将在没有空间时换行

我删除/调整了您的 flex 属性：

html,
body {
  height: 100%;
}
.row-flex,
.row-flex > div[class*='col-'] {
  display: flex;
  flex-wrap: wrap;
  flex: 1 1 auto;
}
.row-flex > div[class*='col-'] div {
  width: 100%;
}
