我以某种方式设法让几乎所有东西都正常工作。但是框 3 中的按钮并没有立即显示，甚至当你将鼠标悬停在它上面时它也会向上一点。如何解决这个问题我整天都在搜索和调整解决方案。

这是小提琴链接：

HTML 代码：

<div class="box image1">1</div>
<div class="box image1">2</div>
<div class="box image3"><a class='fb_iframe' href="./">
<div align="center">


<br /><br /><br /><br /><br /><br />
<br /><br /><br /><br /><br /><br />
<br /><br /><br /><br /><br /><br />
<div id="btn">
    <span class="plus">OPDRACHT PLAATSEN</span>
</div>

CSS 代码：正文 {

你关闭 .box:hover 然后再关闭它两次。那里缺少样式吗？

http://jsfiddle.net/calder12/2aHeU/22

.box:hover{
  width: 250px;

  margin-top: -18px;
 -moz-box-shadow:    0 0 50px black;
 -webkit-box-shadow: 0 0 50px black;
 box-shadow:         0 0 50px black;    

}
