Question

我有一个带有正面和背面的卡片元素（bootstrap-4），悬停在背面。为了创造一个＆＃34;折角效果＆＃34;我在前卡上使用了一个伪元素（：before），除了firefox之外，它适用于所有浏览器。

伪元素的左下角也应该是圆角的，所以我设置了一个border-radius。不幸的是，在Firefox中，角落没有圆角，而是伪元素中显示了一个奇怪的框。

在Firefox中导致此问题的任何想法？我已经玩过定位，z-index，溢出等等，但我找不到根本原因。

提前多多感谢!!

以下::before伪元素的更改可能对您有用，您还必须为此解决方案添加::after伪元素。

.front::before {
      content: "";
      position: absolute;
      top: 0px;
      right: 0px;
      border-bottom-left-radius: 10px;
      height: 25px;
      width: 25px;
      background: #32a2d4;
}

.front::after {
    content: "";
    position: absolute;
    top: -11px;
    right: -15px;
    height: 25px;
    width: 35px;
    background: white;
    transform: rotate(40deg);
}

在Firefox中border-radius似乎无法正确应用于width和height为0的元素。可能的解决方法是使用{{创建包装器1}}和overflow: hidden本身：

border-radius

.roundArrow {
  border-radius: 0 0 0 10px;
  width: 50px;
  height: 50px;
  overflow: hidden;
}

.roundArrow:after {
  content: "";
  display: block;
  top: 0px;
  right: 0px;
  border-width: 0px 50px 50px 0px;
  border-style: solid;
  border-color: transparent #f6f6f6 #32a2d4 transparent;
}
