如何在js中onclick将div置于前面，调整大小并将其居中到屏幕中间？
请耐心等待，我很难对此给出一个好的解释。
所以我想制作一个信息页面，其中有几个 div 来显示它所包含的信息的一些预览。像这样： 标准视图
当访问者单击其中一个 div 时，它会翻转、增大大小并居中于所有其他 div 之上，而不会影响它们。像这样：
到目前为止，我已经完成了网格结构和翻转，但是一旦我开始摆弄 div 的尺寸，所有东西都会移动：

$(document).on("click", ".flip-container", function () {
$(this).toggleClass('hover');
$('.front').removeClass('front');
$(this).toggleClass('zIndex')
});
.flip-container {
perspective: 1000px;
}
.flip-container.hover .flipper {
transform: rotateY(180deg);
}
.bringToFront {
width: 500px !important;
height: 500px !important;
align-content: center !important;
z-index: 1000 !important;
}
.flip-container,
.front,
.back {
display: inline-flex;
width: 320px;
height: 480px;
}
.flipper {
transition: 0.6s;
transform-style: preserve-3d;
position: relative;
}
.front,
.back {
backface-visibility: hidden;
position: absolute;
top: 0;
left: 0;
}
.front {
z-index: 2;
transform: rotateY(0deg);
}
.back {
transform: rotateY(180deg);
}
.green {
width: 320px;
height: 480px;
background-color: green;
}
.blue {
background-color: blue;
width: 320px;
height: 480px;
}

您需要使用 CSS 位置来实现所需的结果。以下是我对您的代码所做的修改：.card-holder为每个添加一个包装器.flip-container，这对于避免元素移动非常重要，因为.flip-container位置固定，因此其他元素不会移动，因为.card-holder将在那里避免移动。<div class="card-holder"> <div class="flip-container"> <div class="flipper"> <div class="front"> <!-- front content --> <div class="green"> </div> </div> <div class="back"> <!-- back content --> <div class="blue"> </div> </div> </div> </div></div>将此 CSS 添加到.card-holder.card-holder { width: 320px; height: 480px; display: inline-flex;}并从中删除了以下内容.flip-container, .front, .back.flip-container, .front, .back { width: 320px; height: 480px;}在 CSS 中添加了以下动画，在焦点动画上，卡片将被固定，并且大小为 2 倍，在模糊时，卡片将处于初始状态。.focus { animation: focus 0.4s ease-in-out forwards;}.blur { animation: blur 0.4s ease-in-out forwards;}@keyframes focus { to { position: fixed; top: 50%; left: 50%; transform: translate(-50%, -50%) scale(2); z-index: 5; }}@keyframes blur { from { position: fixed; top: 50%; left: 50%; transform: translate(-50%, -50%) scale(2); z-index: 5; }} to { position: relative; top: initial; left: initial; transform: translate(0%, 0%) scale(1); z-index: 0; }}这是我添加的 jquery 代码：if((!$(this).hasClass('focus') && !$(this).hasClass('blur')) || $(this).hasClass('blur')) { // add focus and remove blur class for initial state as well as if blur class is available $(this).addClass('focus'); $(this).removeClass('blur');}else if ($(this).hasClass('focus')) { // add blur and remove focus class if focus class is available $(this).addClass('blur'); $(this).removeClass('focus');}// to stop event propagation to other elementsevent.stopPropagation()查看实际效果：https://jsfiddle.net/8jh4pwut/15/ $(document).on("click", ".flip-container", function (event) { $(this).toggleClass('hover'); $('.front').removeClass('front'); $(this).toggleClass('zIndex'); if((!$(this).hasClass('focus') && !$(this).hasClass('blur')) || $(this).hasClass('blur')) { $(this).addClass('focus'); $(this).removeClass('blur'); } else if ($(this).hasClass('focus')) { $(this).addClass('blur'); $(this).removeClass('focus'); } event.stopPropagation() });.flip-container { perspective: 1000px;}.flip-container.hover .flipper { transform: rotateY(180deg);}body { margin: 0;}.bringToFront { width: 500px !important; height: 500px !important; align-content: center !important; z-index: 1000 !important;}.card-holder { width: 320px; height: 480px; display: inline-flex;}.flip-container,.front,.back { display: inline-flex;}.flipper { transition: 0.6s; transform-style: preserve-3d; position: relative;}.front,.back { backface-visibility: hidden; position: absolute; top: 0; left: 0;}.front { z-index: 2; transform: rotateY(0deg);}.back { transform: rotateY(180deg);}.green { width: 320px; height: 480px; background-color: green;}.blue { background-color: blue; width: 320px; height: 480px;}.focus { animation: focus 0.4s ease-in-out forwards;}.blur { animation: blur 0.4s ease-in-out forwards;}@keyframes focus { to { position: fixed; top: 50%; left: 50%; transform: translate(-50%, -50%) scale(2); z-index: 5; }}@keyframes blur { from { position: fixed; top: 50%; left: 50%; transform: translate(-50%, -50%) scale(2); z-index: 5; }} to { position: relative; top: initial; left: initial; transform: translate(0%, 0%) scale(1); z-index: 0; }}<!DOCTYPE html><html><head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Document</title> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript"></script></head><body><div class="overlay"></div> <div style="display: flexbox; align-content: center; width: 100%; position:absolute"></div> <div class="card-holder"> <div class="flip-container"> <div class="flipper"> <div class="front"> <!-- front content --> <div class="green"> </div> </div> <div class="back"> <!-- back content --> <div class="blue"> </div> </div> </div> </div> </div> <div class="card-holder"> <div class="flip-container"> <div class="flipper"> <div class="front"> <!-- front content --> <div class="green"> </div> </div> <div class="back"> <!-- back content --> <div class="blue"> </div> </div> </div> </div> </div></body> <script></script></html> -

最好、最简单的方法是使用 JavaScript。解释位于代码片段下方。function hello() { document.getElementById('div').classList.add('anim'); setTimeout(function(){ document.getElementById('div').classList.remove('anim'); }, 1000); }#div{ height: 100px; width: 100px; background-color: yellow;}.anim { animation: anim 1s;}@keyframes anim { to { background-color: red; }}<div id="div" onclick="hello()"></div>现在，在CSS中，我们创建了带有一些样式的 div，并且创建了带有动画样式的单独的 class。然后像往常一样，我们将关键帧规则添加到动画中。然后在我们的JS中，我们有一个函数将该类添加到我们的 div 中。然后我们设置一个超时函数，它的时间指定为动画的长度（以毫秒为单位），这将从 div 中删除动画类。然后在HTML中，我们指定hello()function 作为onclickdiv 的属性。就是这样。
