Question

我正在努力实现same effect here所以当你将鼠标悬停在div上时，它会折叠并显示内容，但我无法弄清楚如何执行此操作。

到目前为止，我可以使用以下代码将内容滑入。下面的代码和jsfiddle can be seen here。

HTML

<div class="artist artist-1"></div>
<div id="artist-text">Hi there</div>

CSS

.artist-1:hover + #artist-text {
  display: block;
}

#artist-text {
  display: none;
  background-color: #000000;
  width: 130px;
  padding: 10px;
  position: absolute;
  left: 50%;
  top: 60%;
  animation-duration: 1s;
  animation-name: slideLeft;
}

.artist {
  height: 100px;
  width: 100px;
}

.artist-1 {
  background-color: red;
  position: absolute;
  left: 20%;
  top: 40%;
}

@keyframes slideLeft {
  from {
    margin-left: 100%;
    width: 100%; 
  }

  to {
    margin-left: 0%;
    width: 100%;
  }
}

I'm going to try and guide you in the right direction. They're using 3D transforms to create the flip card effect, alongside the transform-origin property. Here's a link to a tutorial showing an effect on which you can base your code:

https://desandro.github.io/3dtransforms/docs/card-flip.html

Also, here's a live example. It's probably not exactly what you need, but it will help you.

.card, .card-flip {
  position:absolute;
  display:block;
  background:lightgreen;
  width:200px;
  height:300px;
}

.card {
  z-index:1;
}

.container {
  perspective: 800px;
}

.card-flip {
  background:lightblue;
  margin-left:200px;
  transition: transform 1s;
  transform-origin:left;
  transform:rotateY(120deg);
  z-index:0;
}

.container:hover .card-flip {
  transform:rotateY(0deg);
}

<div class="container">
  <div class="card"></div>
  <div class="card-flip"></div>
</div>

动画处于：悬停，它被称为翻转卡效果。

你可以通过改变变换来改变效果。过渡价值观。

.background-info .text {

.background-out {

}
.background-over {
  background-color: green;

  opacity: 0;
  transform-origin: 100% 50% 0px;
  transform: rotateY(-90deg);
}
.wrapper:hover .background-out {
  visibility: hidden;
}
.wrapper:hover .background-over,
.wrapper:hover .background-info {
  transform: translate3d(0px,0px,0px) rotateY(0deg);
  transition: opacity 600ms cubic-bezier(0.55, 0.31, 0.15, 0.93) 0ms,
-moz-transform 600ms cubic-bezier(0.55, 0.31, 0.15, 0.93) 0ms,
-webkit-transform 600ms cubic-bezier(0.55, 0.31, 0.15, 0.93) 0ms;
  visibility: visible;
  opacity: 1;
