卡片翻转没有显示回来。翻转时正面保持可见答案

【问题标题】：Card flip not showing back. Front stays visible when flipped卡片翻转没有显示回来。翻转时正面保持可见
【发布时间】：2022-02-01 01:35:11
【问题描述】：

我正在尝试创建一个翻转卡片以最大化网页上的空间。当我切换 FlipCard 功能时，卡片会翻转但不显示背面，而正面仍然可见但被镜像。有谁知道为什么会这样？卡片正面由标题组成，背面是 UL。

感谢您的帮助和您的时间！

我不知道为什么，但删除 backdrop-filter 使其工作。

请阅读更多关于这个问题from this post

您可以使用-webkit-backdrop-filter: blur(10px); 作为解决方法，我已经更新了代码...

const card = document.getElementById("card")

card.addEventListener("click", flipCard);

function flipCard() {
  card.classList.toggle("flipCard");
}

.cards {
    background: linear-gradient(

    rgba(52, 52, 52, 0.4),
    rgba(52, 52, 52, 0.1));
    /*backdrop-filter: blur(10px);*/
    -webkit-backdrop-filter: blur(10px);
    border-radius: 10px;
    box-shadow: rgba(0, 0, 0, 0.24) 0px 3px 8px;
    position: relative;
    transform-style: preserve-3d;

.card-front {

    width: 100%;
    height: 100%;

    transform: rotateY(180deg);
    backface-visibility: hidden;
