Question

我尝试创建一个CSS动画，当你将鼠标悬停在框上时，它会使用CSS动画显示div。我使用以下网站作为参考。 click here然而我似乎无法实现efx。在我的网站上，我使用JqUERY进行显示和隐藏功能，我的addClass和RemoveClass工作但整体而言，该功能不起作用。有人能引导我朝着正确的方向前进。

/ ** HTML * * /

div class="box">
        <div class="trigger">hhh</div>
            <div class="overlay">
                <h1>box 1</h1>
            </div>
        </div>

<div class="box">
<div class="trigger">hhh</div>
      <div class="overlay">
            <h1>box 1</h1>
        </div>
    </div>

<div class="box">
<div class="trigger">hhh</div>
    <div class="overlay">
            <h1>box 1</h1>
        </div>
    </div>

/ * jquery ** /

                     $(".overlay").addClass("visible");
        $(".overlay").removeClass("visible");
            $(".trigger").hover(function(){
                var $this = $(this);
                $this.next(".overlay").addClass("visible");
            }); 

            $(".trigger").mouseleave(function(){
                var $this = $(this);
                $this.next(".overlay").removeClass("visible");
            });

/ ** CSS ANIMATION ** /

.fadeInDown {
-webkit-animation-name: fadeInDown;
-moz-animation-name: fadeInDown;
-o-animation-name: fadeInDown;
animation-name: fadeInDown;
-webkit-animation-duration: 1s;
-webkit-animation-delay: 2s;
-webkit-animation-timing-function: ease;
-webkit-animation-fill-mode: both;

-moz-animation-duration: 1s;

     @-webkit-keyframes fadeInDown {
0% {
    opacity: 0;
    -webkit-transform: translateY(-20px);
}

100% {
    opacity: 1;
    -webkit-transform: translateY(0);
}
      }


     .fadeInUp {

animation-duration: 1s;
animation-delay: 2s;
animation-timing-function: ease;
animation-fill-mode: both;
        }

      @-Webkit-keyframes fadeInUp {
0% {

    -moz-transform: translateY(20px);
}

Answer 1

尝试使用您提供的css类，并将第二个参数传递给“addClass”调用，指示它应该设置动画的毫秒数。例如：

$(".trigger").hover(function(){
    var $this = $(this);
    $this.next(".overlay").addClass("fadeInDown", 1000);
});

Answer 2

添加以下css和HTML标记。

HTML代码： -

<h1 class="animated fadeInUp" >Example</h1>

CSS代码： -

.animated {
  -webkit-animation-duration: 1s;
  animation-duration: 1s;
  -webkit-animation-fill-mode: both;
  animation-fill-mode: both;
}
@keyframes fadeInUp {
  from {
    opacity: 0;
    -webkit-transform: translate3d(0, 100%, 0);
    transform: translate3d(0, 100%, 0);
  }

  to {
    opacity: 1;
    -webkit-transform: none;
    transform: none;
  }
}

.fadeInUp {
  -webkit-animation-name: fadeInUp;
  animation-name: fadeInUp;
}

FadeInUp css动画无法正常工作
