Question

我目前正在尝试为网站创建一个特殊的悬停。

以下是我要做的事情：

4个区块，所有区块都响应黑色条形，主要文本的不透明度为70％。

然后当我悬停一个区块时，黑色条填满底部的所有空间并显示2或4个按钮。

也许是这样的：

<div class="image-block">
    <div class="image1">
        <span class="black-bar">SOME TEXT</span>
        <button class="special-button">Button</button>
        <button class="special-button">Button</button>
    </div>
    <div class="image2">
        <span class="black-bar">SOME TEXT</span>
        <button class="special-button">Button</button>
        <button class="special-button">Button</button>
    </div>
    <div class="image3">
        <span class="black-bar">SOME TEXT</span>
        <button class="special-button">Button</button>
        <button class="special-button">Button</button>
        <button class="special-button">Button</button>
        <button class="special-button">Button</button>
    </div>
    <div class="image4">
        <span class="black-bar">SOME TEXT</span>
        <button class="special-button">Button</button>
        <button class="special-button">Button</button>
    </div>
</div>

但对于CSS，我真的不知道如何做到这一点。用完全响应的东西做最简单最好的方法是什么？

谢谢！

Answer 1

查看下面的代码（我必须使用jQuery）或this fiddle

＆＃13;

$('.text').mouseenter(function () {
	$('.hovering').animate({'height': '200px'}, 'slow');
});
$('.image').mouseleave(function () {
	$('.hovering').animate({'height': '100px'}, 'slow');
});

＆＃13;

.image {
  position: relative;
  background-image: url(http://www.w3schools.com/css/trolltunga.jpg);
  height: 300px;
  width: 600px;
}
.hovering {
  display: block;
  height: 100px;
  width: 600px;
  background-color: rgba(0,0,0,0.7);
  overflow: hidden;
  margin-top: 100px; 
  position: absolute;
}
button, .text {
  display: block;
  width: 130px; height: 40px;
  margin: 0 auto;
}
.text {
  color: white;
  font-size: 40px;
  text-align: center;
  padding-top: 30px;
  width: 200px;
  margin-bottom: 30px;
  display: block;
  
}

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="image">
<div class="hovering">
   <span class="text">Text here</span>
   <button>Button here</button>
</div>
</div>
The black box shrinks when mouse leaves the image

Answer 2

这是一个纯css选项。如果我错过了什么，请告诉我。我不得不稍微调整你的标记。

＆＃13;

.image-block{
  display: flex;
  flex-direction: row;
}

.col{
  display: flex;
  flex-direction: column;
}

.image1, .image2, .image3, .image4{
  background: url(http://lorempixel.com/output/nature-q-c-640-480-1.jpg) no-repeat center center;
  background-size: cover;
  width: 200px;
  margin: 0 20px 20px 0;
  position: relative;
  overflow: hidden;
}

.image1, .image4{
  height: 100px;
}

.image2, .image3{
  height: 200px;
}

.black-bar{
  background: rgba(0,0,0,0.4);
  text-align: center;
  color: #fff;
  width: 100%;
  top: 50%;
  position: absolute;
  margin-top: -18px;
  padding: 10px 0;
  font-family: Helvetica, Arial, sans-serif;
  transition: all 0.5s ease;
  bottom: calc(50% - 15px);
  overflow: hidden;
}

.black-bar button{
  margin: 10px;
  display: none;
  border: none;
  background: #fff;
}

.black-bar p{
  margin: 0;
  font-weight: 200;
  font-size: 12px;
}

.image1:hover .black-bar, .image2:hover .black-bar, .image3:hover .black-bar, .image4:hover .black-bar{
  bottom: 0;
  transition: all 0.5s ease;
}

.image1:hover .black-bar button, .image2:hover .black-bar button, .image3:hover .black-bar button, .image4:hover .black-bar button{
  display: inline-block;
}

＆＃13;

<div class="image-block">
  <div class="col">
    <div class="image1">
        <div class="black-bar">
          <p>SOME TEXT</p>
          <button class="special-button">Button</button>
          <button class="special-button">Button</button>

          <button class="special-button">Button</button>
          <button class="special-button">Button</button>
        </div>
    </div>
  </div>
  <div class="col">
    <div class="image3">
        <div class="black-bar">
          <p>SOME TEXT</p>
          <button class="special-button">Button</button>
          <button class="special-button">Button</button>
          <button class="special-button">Button</button>
          <button class="special-button">Button</button>
        </div>
    </div>
    <div class="image4">
        <div class="black-bar">
          <p>SOME TEXT</p>
          <button class="special-button">Button</button>
          <button class="special-button">Button</button>

</div>
