3D flip animation not working in chrome

I wanted to create a card with text that will flip and show the back with some other text whenever you click on a "card" (div). I checked all errors and stuff, but somehow didn't work on chrome.

HTML:

<div class="card effect__EFFECT">
  <div class="card__front">
    <span class="card__text">front</span>
  </div>
  <div class="card__back">
    <span class="card__text">back</span>
  </div>
</div>

      

        
        
        
      

    

CSS

.card {
  position: relative;
  float: left;
  padding-bottom: 25%;
  width: 25%;
  text-align: center;
}

.card__front,
.card__back {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
}

.card__front,
.card__back {
  -webkit-backface-visibility: hidden;
          backface-visibility: hidden;
  -webkit-transition: -webkit-transform 0.3s;
          transition: transform 0.3s;
}

.card__front {
  background-color: #ff5078;
}

.card__back {
  background-color: #1e1e1e;
  -webkit-transform: rotateY(-180deg);
          transform: rotateY(-180deg);
}

.card.effect__click.flipped .card__front {
  -webkit-transform: rotateY(-180deg);
          transform: rotateY(-180deg);
}

.card.effect__click.flipped .card__back {
  -webkit-transform: rotateY(0);
          transform: rotateY(0);
}

      

        
        
        
      

    

JavaScript:

(function() {
  var cards = document.querySelectorAll(".card.effect__click");
  for ( var i  = 0, len = cards.length; i < len; i++ ) {
    var card = cards[i];
    clickListener( card );
  }

  function clickListener(card) {
    card.addEventListener( "click", function() {
      var c = this.classList;
      c.contains("flipped") === true ? c.remove("flipped") : c.add("flipped");
    });
  }
})();
