使用 3d css 转换翻转时，Firefox 不会隐藏卡片的背面

Question

我正在使用 CSS 3d 过渡在卡片的背面放置一些文本。悬停时，卡片会翻转并显示文本。

这在 Chrome 上效果很好；但是，在 Firefox 上，卡片的正面在翻转时仍然可见。

谁能帮助我使用适用于所有浏览器的 CSS？

Answer 1

没关系，在这里找到答案：Backface-Visibility Not Working Properly in Firefox (Works in Safari)。

关键是在卡片的正反面加上transform: rotateX(0);。

将backside-visibility: hidden; 添加到容器中也可以，但它会使鼠标无法访问卡片的背面，即您无法单击背面的链接。

我不知道为什么会这样，但显然它在 Firefox 中已经存在三年了：https://bugzilla.mozilla.org/show_bug.cgi?id=1201471
