html - 如何在悬停时展开 div 及其内容？

Question

我正在尝试创建一个在悬停时展开的 div，但无法弄清楚如何使内容随 div 一起展开。我尝试了一些溢出选项，但它们没有用。

.grow {
  padding: 5px 5px 5px 5px;
  border-radius:10px;
    height: 50px; 
    width: 22%; 
    margin: 5px 1% 5px 1%; 
    float: left; 
    position: relative; 
    transition:height 0.5s; 
    -webkit-transition:height 0.5s; 
    text-align: center;

}
.grow:hover {
    height: 115px; /* This is the height on hover */
}

<div class="grow" style="background-color: #2a75a9;">
    <h2>Title</h2> <br>
    Contrary to popular belief, Lorem Ipsum is not simply random text.  It has roots in a piece of classical Latin literature
</div>

这是 JSFiddle

Answer 1

添加overflow: hidden到父(.grow)容器隐藏描述。这将在悬停时显示描述。

此外，不要使用 <br />标记，将文本包装在 <p> 中标签。

.grow {
  padding: 5px 5px 5px 5px;
  border-radius: 10px;
  height: 49px;
  width: 22%;
  margin: 5px 1% 5px 1%;
  float: left;
  position: relative;
  transition: height 0.5s;
  -webkit-transition: height 0.5s;
  text-align: center;
  overflow: hidden;
}
.grow:hover {
  height: 145px;
}

<div class="grow" style="background-color: #2a75a9;">
  <h2>Title</h2> 
  <p>Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature</p>
</div>
