Card flip not showing back. Front stays visible when flipped-CodePudding

I am trying to create a flip card to maximize space on a webpage. When I toggle the flipCard function, the card flips but doesn't show the back and the front remains visible but is mirrored. Does anyone know why this is happening? The front of the card will consist of headings and the back is a UL.

Thanks for any help and your time!

const card = document.getElementById("card")

card.addEventListener("click", flipCard);

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

.cards {
    background: linear-gradient(
    to bottom,
    rgba(52, 52, 52, 0.4),
    rgba(52, 52, 52, 0.1));
    backdrop-filter: blur(10px);
    border-radius: 10px;
    box-shadow: rgba(0, 0, 0, 0.24) 0px 3px 8px;
    position: relative;

    transition: all 0.8s ease;
    z-index: 10;

I am not sure why but removing the backdrop-filter makes it work.

Please read more about this problem from this post

You can use -webkit-backdrop-filter: blur(10px); as a work around, I haveupdated the code...

const card = document.getElementById("card")

card.addEventListener("click", flipCard);

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

.cards {
    background: linear-gradient(
    to bottom,

    /*backdrop-filter: blur(10px);*/
    -webkit-backdrop-filter: blur(10px);
