纯CSS手风琴功能

标签： html css

我在下面有一个纯CSS手风琴列表的代码。我想知道是否有可能将标题下的文本放在像这里的示例中那样：http://codepen.io/pirrera/pen/KwzMGZ，但仅使用纯CSS？任何事都有帮助，欢呼。

是的，您可以使用transform: scale()缩小内容并使用opacity: 0隐藏内容，然后在标签/输入为:checked时将其转换为正常值

选中复选框后，您可以为段落的比例设置动画

.input:checked~.tab-content p {
  transform: scale(1);
}

请参阅以下代码：

.wrapper {
  max-width: 960px;
  margin: 0 auto;
}


/* Acordeon styles */

.tab {
  position: relative;
  margin-bottom: 1px;
  width: 100%;
  color: #005bab;
  overflow: hidden;
}

.input {
  position: absolute;
  opacity: 0;
  z-index: -1;
}

.label {
  position: relative;
  text-align: center;
  display: block;
  padding: 0 0 0 1em;
  background: #e2ecf6;
  font-size: 14px;
  font-family: Verdana;
  font-weight: bold;
  line-height: 6;
  cursor: pointer;
}

.tab-content {
  max-height: 0;
  overflow: hidden;
  padding: 0px;
  -webkit-transition: max-height .5s;
  -o-transition: max-height .5s;
  transition: max-height .5s;
  padding-left: 20px;
  background: #c3d7ea;
}

.tab-content .container {
  padding: 1em;
  margin: 0;
  transform: scale(0.6);
  -webkit-transition: transform .5s;
  -o-transition: transform .5s;
  transition: transform .5s;
  background: #f4f8fc;
}


/* :checked */

.input:checked~.tab-content {
  max-height: 10em;
}

.input:checked~.tab-content .container {
  transform: scale(1);

使用transform: scale()来＆＃34;成长＆＃34; /＆＃34;缩小＆＃34;内容和效果的过渡。

笔：https://codepen.io/kjkta/pen/MmLewZ

我已添加：

.tab-content {
    transition: .5s transform;
    transform: scale(.1);
}
.input:checked ~ .tab-content {
    transform: scale(1);
}

<强> EDITED

这是一个简单而实用的示例：但是，您无法使用css模拟“onclick”事件。您还可以查看此帖子以获得更多说明：Can I have an onclick effect in CSS?

如果您不介意在代码中使用一些纯JavaScript，请参阅此示例：

https://jsfiddle.net/8xs83phb/

如果您想要一个基于“悬停”事件的手风琴，请参阅以下代码。

ul {
  margin: 0;
  padding: 0;
}

ul li {
  list-style-type: none;
}

h2 {
  margin: 0;
  text-align: center;
  font: normal 22px Arial, Verdana;
}

.box {
  width: 200px;
  max-height: 40px;
  padding: 10px 0;
  background: #fdfdfd;
  box-sizing: border-box;
  overflow: hidden;
  cursor: pointer;
  border-bottom: 1px solid black;
  transition: all 0.5s;
}

.box:hover {
  max-height: 300px;
}
<ul>
  <li>
    <div class='box'>
      <h2>Item One</h2>
      <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Tenetur, architecto, explicabo perferendis nostrum, maxime impedit atque odit sunt pariatur illo obcaecati soluta molestias iure facere dolorum adipisci eum? Saepe, itaque.</p>
    </div>
  </li>
  <li>
    <div class='box'>
      <h2>Item Two</h2>
      <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Tenetur, architecto, explicabo perferendis nostrum, maxime impedit atque odit sunt pariatur illo obcaecati soluta molestias iure facere dolorum adipisci eum? Saepe, itaque.</p>
    </div>
  </li>
  <li>
    <div class='box'>
      <h2>Item Three</h2>
