使 div 高度适合隐藏的悬停内容

Question

我为画廊类别创建了一系列图片链接。每个“按钮”在背景中都有一个图像，并且画廊标题覆盖它。我已将其设置为更改背景，并且标题也更改为使用 css 悬停时的画廊，但我遇到的问题是高度。正在加载 div 以适应标题，但随后在鼠标悬停时跳得更大以容纳描述文本。我需要它加载足够大以使描述文本很好地适合其中。

我希望它具有响应性，因此文本需要能够换行，并且 div 需要相应地扩展（并且永远不会在鼠标悬停时跳跃高度）。所以高度不能是固定的高度，否则当 div 是全宽时，这些高度会太高。我在这里设置了一个测试

body{
    font-family: Arial, Helvetica, sans-serif;
}



.item1{
    width: auto;
     display: table-cell;
        
}
a{
    text-decoration:none;
}
.label1 {
    padding-top: 20px;
    padding-bottom: 20px;
    text-align: center;
    font-size: 24px;
    font-weight: bold;
    color: #ffffff;
    text-transform: uppercase;
    white-space: nowrap;
    text-decoration: none;
    background: url('https://premium.wpmudev.org/blog/wp-content/uploads/2015/02/fullwidth-small.png') no-repeat; 
    background-position: center top;
    background-size: 100% auto;
    transition: background 0.5s ease;

}
.label1.success {
    background-color: #FFFFFF;
}

.label1:hover {
    width: auto;
    height: auto;
    padding-left: 20px;
    padding-right: 20px;
    background: #FFFFFF ;
    background-position: center top;
    background-size: 100% auto;
     -webkit-box-shadow:inset 0px 0px 0px 4px #000000;
    -moz-box-shadow:inset 0px 0px 0px 4px #000000;
    box-shadow:inset 0px 0px 0px 4px #000000;
}

.item1 a p.new-label1 span{
  position: relative;
  content: 'NEW'
}
.item1:hover a p.new-label1 span{
  display: none;
}
.item1:hover a p.new-label1:after{
    content:attr(data-title);
    white-space: normal !important;
    overflow-wrap: normal;
    font-size: 14px;
    color: #000000;
}

<div style="width: 50%; display: table;">

<div class="item1">


    <a href="">
         <p class="label1 success new-label1" data-title="I Show up on Hover and have lots and lots of things to say and it takes up too much space" ><span class="align">New</span></p>
    </a>
</div>


</div>
<div class="cleafix">
</div>

我也遇到了过渡效果的问题，但这个问题要紧迫得多。也就是说，如果有人想给我一个解决方案，我一点也不介意；）

我不知道这正是你想要的，但我根据自己的理解做了演示。它可能会有所帮助

body {
	font-family: Arial, Helvetica, sans-serif;
}
.item1 {
	width: auto;
	display: table-cell;
}
a {
	text-decoration: none;
}
.label1 {
	position: relative;
	text-align: center;
	font-size: 24px;
	font-weight: bold;
	color: #ffffff;
	text-transform: uppercase;
	white-space: nowrap;
	text-decoration: none;
	background: url('https://premium.wpmudev.org/blog/wp-content/uploads/2015/02/fullwidth-small.png') no-repeat;
	background-position: center top;
	background-size: cover;
	transition: all .4s;
	margin: 0;
}
.label1.success {
	background-color: #fff;
}
.item1:hover .label1 {
}
.item1 a p.new-label1 span {
	content: 'NEW';
	position: absolute;
	right: 0;
	left: 0;
	top: 50%;
	transform: translateY(-50%);
	opacity: 1;
	visibility: visible;
	transition: all .4s;
}
.item1:hover a p.new-label1 span {
	opacity: 0;
	visibility: hidden;
}
.item1 a p.new-label1:after {
	content: attr(data-title);
	background-color: transparent;
	white-space: normal;
	overflow-wrap: normal;
	font-size: 14px;
	color: #000;
	padding: 20px 10px;
	opacity: 0;
	visibility: hidden;
	display: block;
	transition: all .4s;
}
.item1:hover a p.new-label1:after {
	content: attr(data-title);
	background-color: #fff;
	opacity: 1;
	visibility: visible;
	-webkit-box-shadow: inset 0px 0px 0px 4px #000000;
	-moz-box-shadow: inset 0px 0px 0px 4px #000000;
	box-shadow: inset 0px 0px 0px 4px #000000;
}

<div style="width: 50%; display: table;">
    <div class="item1">
        <a href="">
             <p class="label1 success new-label1" data-title="I Show up on Hover and have lots and lots of things to say and it takes up too much space" ><span class="align">New</span></p>
        </a>
    </div>
</div>
<div class="cleafix"></div>
