使div折叠显示内容 [英] make a div fold out to show content

问题描述

我想实现此处的相同效果，因此当您将鼠标悬停在div上时，显示内容，但我不知道该如何做。

I am trying to achieve the same effect here so when you hover on the div it folds out and shows the content, but I cannot figure out how to do this.

到目前为止，我可以使用下面的代码使内容幻灯片。下面的代码和 jsfiddle可在此处查看。

So far I am able to make the content slide in by using the following code. Code underneath and jsfiddle can be seen here.

html

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%;
  }
}

推荐答案

动画处于：hover，它称为翻转卡效果。

The animation is in :hover, it's called the flip card effect.

您可以通过使用transform&过渡值。

You can alter the effect by playing around with the transform & transition values.

立方贝塞尔，如果您想知道在哪里获取立方贝塞尔函数的值。

Cubic bezier if you're wondering where to get the values for the cubic-bezier function.

.outer-wrapper {
  position: absolute;
  left: 0;
  top: 0;
}
.outer-wrapper:nth-child(2) {
  left: 600px;
}
.outer-wrapper:nth-child(3) {
  top: 300px;
}
.wrapper {
  position: relative;
  width: 200px;
  height: 200px;
  margin: 0 0 20px;
}
.background-out,
.background-over {
  position: absolute;
  left: 0;
  top: 0;
  width: 100%;
  height: 100%;
}
.background-info {
  position: absolute;
  left: 200px;
  top: 0;
  width: 100%;
  height: 100%; 
  visibility: hidden;
  opacity: 0.2;
  transform-origin: 0% 50% 0px;
  transform: rotateY(-90deg);
  background-color: grey;
}
.background-info .text {
  padding: 5px;
}
.background-out {
  background-color: red;
}
.background-over {
  background-color: green;
  visibility: hidden;
  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;
}

  <div class="outer-wrapper">
    <div class="wrapper">
      <div class="background-out"></div>
      <div class="background-over"></div>
      <div class="background-info">
        <div class="text">Text 1</div>
       </div>
    </div>    
  </div>
  <div class="outer-wrapper">
    <div class="wrapper">
      <div class="background-out"></div>
      <div class="background-over"></div>
      <div class="background-info">
        <div class="text">Text 2</div>
       </div>
    </div>    
  </div>
  <div class="outer-wrapper">
    <div class="wrapper">
      <div class="background-out"></div>
      <div class="background-over"></div>
      <div class="background-info">
        <div class="text">Text 2</div>
