Firefox-CSS:伪元素“之前"的边界半径问题. [英] Firefox-CSS: border-radius issue for pseudo-element "before"

问题描述

我有一个正面和背面的卡片元素(bootstrap-4)，在背面上显示了悬停.为了创建折角效果"，我在前面的卡上使用了伪元素(:before)，该元素对除firefox以外的所有浏览器都适用.

I have a card-element (bootstrap-4) with a front and back, on hover the back side is shown. In order to create a "folded corner effect" I am using a pseudo-element(:before) on the front card, which works fine for all browsers except of firefox.

伪元素的左下角也应该被弄圆，所以我设置了一个边界半径.不幸的是，在Firefox中，角不是圆角的，而是在伪元素中显示了一个奇怪的框.

The bottom-left corner of the pseudo-element should also be rounded, so I set a border-radius. Unfortunately in Firefox the corner is not rounded, instead there is a strange box shown in the pseudo-element.

有什么想法在Firefox中导致此问题吗?我已经尝试过定位，z-index，溢出等问题，但是找不到根本原因.

Any ideas what is causing this issue in Firefox? I already played around with positioning, z-index, overflow etc. but I cannot find the root cause.

非常感谢！

推荐答案

在Firefox中， border-radius 似乎未正确应用于具有 width 的元素，并且 height 设置为0.一种可能的解决方法是使用自己的 overflow:hidden 和 border-radius 制作包装器:

In Firefox border-radius doesn't seem to get properly applied to elements with a width and height of 0. A possible workaround to this would be to make a wrapper with overflow: hidden and a border-radius on its own:

.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;
}

<div class="roundArrow"></div>
