翻转css 3+js卡，只会一起翻转

Question

嘿，我在这里找到了一个很好的IE兼容卡翻转代码，我对它进行了修改，到目前为止它仍然有效。唯一的问题是它会翻转所有的牌，而不是选中的一张。我试图修改js代码，但不知何故它不起作用：

html:

<div class="c-services__item">
  <div class="c-services__item__content">
   <div class="c-services__item--front">Front</div>
   <div class="c-services__item--back">Back</div>
  </div>
 </div>
<div class="c-services__item">
  <div class="c-services__item__content">
   <div class="c-services__item--front">Front</div>
   <div class="c-services__item--back">Back</div>
  </div>
 </div>

js:

 $('.c-services__item').hover(function(){$('.c-services__item').toggleClass('applyflip');}.bind(this));

我试图将其修改为：

    $(".c-services__item").hover(function(){
        $(this).find(".c-services__item").toggleClass("applyflip");}.bind(this));
    });
});

但是根本不起作用

css：

.c-services__item {
    perspective: 1000px;
    -webkit-perspective: 1000px;
    -moz-perspective: 1000px;
    -o-perspective: 1000px;

.c-services__item .c-services__item__content {

您不需要使用.find()。

$(".c-services__item").hover(function(){
    $(this).toggleClass("applyflip");
