如何使用 CSS 翻转多个 div?

How to flip multiple divs using CSS?

当我使用 CSS3 单击菜单时,如何翻转多个 div

This 代码仅适用于最后两个 divs :

HTML代码

<ul class="nav">
   <li><a href="#home">home</a></li>
   <li><a href="#about">about</a></li>
   <li><a href="#work">work</a></li>
   <li><a href="#contact">contact</a></li>
</ul>
<section class="container">
   <div id="card">
      <div class="front flipper" id="home">home</div>
      <div class="back flipper" id="about">about</div>
      <div class="front flipper" id="work">work</div>
      <div class="back flipper" id="contact">contact</div>
   </div>
</section>

CSS代码

    .container {
    width: 500px;
    height: 360px;
    position: relative;
    margin: 0 auto 40px;
    border: 1px solid #CCC;
    -webkit-perspective: 800px;
    -moz-perspective: 800px;
    -o-perspective: 800px;
    perspective: 800px;
}
#card {
    width: 100%;
    height: 100%;
    position: absolute;
    -webkit-transition: -webkit-transform 1s;
    -moz-transition: -moz-transform 1s;
    -o-transition: -o-transform 1s;
    transition: transform 1s;
    -webkit-transform-style: preserve-3d;
    -moz-transform-style: preserve-3d;
    -o-transform-style: preserve-3d;
    transform-style: preserve-3d;
}
#card.flipped {
    -webkit-transform: rotateX( 180deg);
    -moz-transform: rotateX( 180deg);
    -o-transform: rotateX( 180deg);
    transform: rotateX( 180deg);
}
#card .flipper {
    display: block;
    height: 100%;
    width: 100%;
    line-height: 260px;
    color: white;
    text-align: center;
    font-weight: bold;
    font-size: 140px;
    position: absolute;
    -webkit-backface-visibility: hidden;
    -moz-backface-visibility: hidden;
    -o-backface-visibility: hidden;
    backface-visibility: hidden;
}
.flipper {
    background: #963
}
#card .front {
    background: red;
}
#card .back {
    background: blue;
    -webkit-transform: rotateX( 180deg);
    -moz-transform: rotateX( 180deg);
    -o-transform: rotateX( 180deg);
    transform: rotateX( 180deg);
}

JavaScript代码

   $(".nav li").on("click", function() {

    var activeTab = $(this).find("a").attr("href");

    //  alert(activeTab);

    if ($("#card").hasClass("flipped")) {
        $("#card").removeClass("flipped");
    } else {
        $("#card").addClass("flipped");
    }

    return false;
});

有什么建议吗?

我认为您只看到最后两个,因为它们堆叠在前两个之上。本质上,卡片本身(带有 .front/.back 类 的元素)在您围绕它们旋转 #card 时保持静止。

或许您可以尝试单独旋转 .front/.back 元素。这意味着手动处理交互,但在我看来它更容易推理。

希望对您有所帮助

与两个元素一起使用时的翻转动画非常简单,因为有一个背面和一个正面。但是当同样的东西需要用很多元素来实现时,它就变得格外复杂,因为你需要维护 3 个状态,如下所示:

  • 翻转 - 这是当方块进入视野并且旋转为 0 度(基本上没有旋转)。
  • 之前 - 这是翻转元素之前的元素状态。在此状态下,块沿一个方向旋转 180 度。
  • After - 这是翻转元素之后的元素状态。在此状态下,块沿相反方向旋转 180 度。

所以基本上当点击 link 时,它之前的方块从 0 度旋转到 180 度,目标方块本身从 -180 度旋转到 0 度(下一个元素保持在 -180 度程度)。做这些事情使它具有链式旋转的外观和感觉。

$(".nav li a").on("click", function() {
  var activeTab = $(this).attr("href");
  $('#card > div').removeClass('flipped after before');
  $(activeTab).addClass('flipped');
  $(activeTab).prevAll('.flipper').addClass('before');
  $(activeTab).nextAll('.flipper').addClass('after');
  return false;
});

Note: The jQuery code can be optimized further but I will leave the fine tuning part to you.

我相信这就是您要找的。

$(".nav li").on("click", function(){
    
    var activeTab = $(this).find("a").attr("href");
    if($(activeTab).hasClass('current-flipper'))
        return;
    //  alert(activeTab);
    $("#card").find('div').removeClass('current-flipper');
    $(activeTab).addClass('current-flipper');
    $("#card").toggleClass("flipped");    
    return false;
});
