Question

我有一个绝对的div在我的页脚后面。当我将鼠标悬停在另一个元素（#sn）上时，我希望该绝对div从页脚后面向上滚动并停在可以看到它的上方。我该怎么做？

＆＃13;

.snapcode-footer { 
  position: absolute;
  padding-top: 20px;
  text-align: center;
  left: 0;
  right: 0;
}

.sub-sub-footer {
  position: relative;
  z-index: 1;
  background-color: #F7F7F7;
  padding-top: 35px;
  padding-bottom: 20px;
}

.sub-footer {
  position: relative;
  z-index: 1;
  background-color: #edeeef;
  margin-top: 0px;
}

＆＃13;

<div class="snapcode-footer">
<img src="https://wumbo.com/wp-content/uploads/2016/11/snapcode.png" width="250px" height="auto" alt="Scan to add us on Snapchat!">
</div>

<div class="sub-sub-footer">
 <ul class="social-footer">
    <li id="twitter"><a href="https://www.twitter.com/wumbo" target="blank"><img src="/wp-content/uploads/2016/11/Twitter-color.png" alt="Follow us on Twitter @wumbo"/></a></li>

 </ul>
</div>

    <div class="sub-footer">
        <div class="container">
            <div class="row">

                <div class="col-md-5-footer">
        <div class="footer-img">    
            <img src="https://www.wumbo.com/wp-content/uploads/2016/11/HullSpar_Slogan.png" alt="Made For The Modern Seafarer™"/>
        <div/>  
                </div>

            </div>

Answer 1

我重新定位了您的div.snapcode页脚并将css属性应用于

#sn：hover~ .snapcode-footer 。希望这会对你有所帮助:)。

＆＃13;

.snapcode-footer { 
  position: absolute;
  padding-top: 90px;
  text-align: center;
  left: 0;
  right: 0;
}

.sub-sub-footer {
  position: relative;
  z-index: 1;
  background-color: #F7F7F7;
  padding-top: 35px;
  padding-bottom: 20px;
}

.sub-footer {
  position: relative;
  z-index: 1;
  background-color: #edeeef;
  margin-top: 0px;
}

#snapchat:hover ~ .snapcode-footer{
  z-index:999;
  color:green;
  position:relative;
  margin-bottom:100px;
  margin-left:50px;
  }

＆＃13;

<div class="sub-sub-footer">
 <ul class="social-footer">
    <li id="twitter"><a href="https://www.twitter.com/hullandspar" target="blank"><img src="/wp-content/uploads/2016/11/Twitter-color.png" alt="Follow us on Twitter @hullandspar"/></a></li>
    <li id="snapchat"><a href="#"><img src="/wp-content/uploads/2016/11/Snapchat-color.png" alt="Follow us on Snapchat @hullandspar"/></a></li>
   <div class="snapcode-footer">
<img src="https://hullandspar.com/wp-content/uploads/2016/11/snapcode.png" width="250px" height="auto" alt="Scan to add us on Snapchat!">
</div>
    <li id="insta"><a href="https://www.instagram.com/hullandspar" target="blank"><img src="/wp-content/uploads/2016/11/Instagram-color.png" alt="Follow us on Instagram @hullandspar"/></a></li>
    <li id="facebook"><a href="https://www.facebook.com/hullandspar" target="blank"><img src="/wp-content/uploads/2016/11/Facebook-color.png" alt="Follow us on Facebook @hullandspar"/></a></li>
 </ul>
</div>

    <div class="sub-footer">
        <div class="container">
            <div class="row">

                <div class="col-md-5-footer">
        <div class="footer-img">    
            <img src="https://www.hullandspar.com/wp-content/uploads/2016/11/HullSpar_Slogan.png" alt="Made For The Modern Seafarer™"/>
        </div>  
                </div>

            </div>

Answer 2

我建议给snapcode-footer一个id，以便更容易控制。

<div class="snapcode-footer" id="snapcode">

<script> var hover = 0; </script>

然后在#sn cargo

上制作一个脚本

<li id="snapchat" onmouseenter =“hover = 1”onmouseout =“hover = 0” ><a href="#"><img src="/wp-content/uploads/2016/11/Snapchat-color.png" alt="Follow us on Snapchat @hullandspar"/></a></li>

最后，如果鼠标悬停在#sn赛车元素上以增加高度或留在一个地方，你可以制作一个脚本

<script>
setInterval("if(hover == 1){snapcode.top--}");
setInterval("if(hover == 0){snapcode.top = 0}");
</script>

如何在将鼠标悬停在另一个元素上时向上滚动div
