css - 透视不适用于 FireFox

Question

在 Chrome 上运行良好，但当我在 FireFox 上尝试时它无法运行。

我已经在互联网上搜索过，但没有找到对我有帮助的东西。

我对转换、动画、过渡等知之甚少，所以我尝试了一些修改并移动了“透视”，但仍然一无所获。

这是 CSS

.uic-wrapper {
  height: 340px;
  width: 300px;
  position: fixed;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
  perspective: 500px;
  perspective-origin: 50% -30%;
}
.uic-wrapper:hover .card-middle {
  transform: translate3d(0, 0, -60px);
  opacity: .8;
}

.uic-wrapper:hover .card-back {
  transform: translate3d(0, 0, -120px);
  opacity: .4;
}

他就是一个很好的例子

$(document).ready(function(){

  "use strict";
  var container = $(".uic-wrapper");
  var nextBtn = $("nav .btn-next");
  var backBtn = $("nav .btn-back");
  var finishBtn = $("nav .btn-finish");

  updateNav();

  function updateNav(){
    var hasAnyRemovedCard = $(".toRight").length ? true : false,
        isCardLast = $(".card-middle").length ? false : true;

    if(hasAnyRemovedCard) {
      backBtn.removeClass('back-btn-hide');

    } else {
      backBtn.addClass('back-btn-hide');
      $(".card-front").addClass('noBack');
    }

    if(isCardLast){
      nextBtn.hide();
      finishBtn.removeClass("hide");
    } else {
      nextBtn.show();
      finishBtn.addClass("hide");
    }
  }

  function showNextCard(){
    //Check if there is only one card left
    if($(".card-middle").length > 0){
      var currentCard = $(".card-front"),
        middleCard = $(".card-middle"),
        backCard = $(".card-back"),
        outCard = $(".card-out").eq(0);

      //Remove the front card
      currentCard.removeClass('card-front').addClass('toRight');
      //change the card places
      middleCard.removeClass('card-middle').addClass('card-front');
      backCard.removeClass('card-back').addClass('card-middle');
      outCard.removeClass('card-out').addClass('card-back');

      updateNav();
    }
  }

  function showPreviousCard(){
    var currentCard = $(".card-front"),
        middleCard = $(".card-middle"),
        backCard = $(".card-back"),
        lastRemovedCard = $(".toRight").slice(-1);

    lastRemovedCard.removeClass('toRight').addClass('card-front');
    currentCard.removeClass('card-front').addClass('card-middle');
    middleCard.removeClass('card-middle').addClass('card-back');
    backCard.removeClass('card-back').addClass('card-out');

    updateNav();
  }

  nextBtn.on('click', function(){
    showNextCard();
  });

  backBtn.on('click', function(){
    showPreviousCard();
  });

});

还有一个 JSFiddle以防万一。

如果似乎没有任何效果，您可以尝试以下 firefox 的解决方法:

@-moz-document url-prefix() {
    .uic-wrapper:hover .card-middle {
        transform: translate3d(14px, -12px, -30px);
        opacity: .8;
        width: 90%;
    }

    .uic-wrapper:hover .card-back {
        transform: translate3d(28px, -24px, -120px);
        opacity: .4;
        width: 80%;
    }
}

我们正在手动设置转换的 X 和 Y 坐标，并设置一些宽度以匹配它的实际外观。
