谁能知道为什么我的翻车会在悬停时弹出。我非常努力地修复，但真的吗？我正在使用 css .hover 函数，请参见下面的示例。任何建议或例子都会感谢我，谢谢炖

    }   
body {
background-color: grey;
background: url(http://wizzfree.com/pix/bg1.jpg) fixed;
background-size: 100% 100%;
background-repeat: no-repeat;
overflow: hidden;
margin: 0px;
    
    font-family: Arial;
    color: darkgrey;
    font-size: 12px;
    line-height: .3;
    letter-spacing: .5px;
}
  .call {
    position: fixed;
    top: 180px;
    left: 50%;
    width: 150px;
    height:123px;
    transform:translateX(-50%); /* center */
    z-index: 3;
}
/*........ crossfade on buttons ........*/

    .hover img{
    transition:.3s;
    position:absolute;
}
    .nohover{
    opacity:0;}
    a:hover .hover{
    opacity:0;
}
    a:hover .nohover{
    opacity:1;
}
    .hover {
    position: relative;
}
    .hover img{
    position: absolute;
}
<div class="call">
<a href="startchat.htm">
<img src="http://wizzfree.com/pix/call2.png" width="150" class="nohover">
<img src="http://wizzfree.com/pix/call3.png" width="150" class="hover"></a>
</div>

你写错了你的CSS。用下面的替换你的CSS。 

body {
  background-color: grey;
  background: url(http://wizzfree.com/pix/bg1.jpg) fixed;
  background-size: 100% 100%;
  background-repeat: no-repeat;
  overflow: hidden;
  margin: 0px;
  font-family: Arial;
  color: darkgrey;
  font-size: 12px;
  line-height: .3;
  letter-spacing: .5px;
}
.call {
    position: fixed;
    top: 180px;
    left: 50%;
    width: 150px;
    height:123px;
    transform:translateX(-50%); /* center */
    z-index: 3;
}

.hover,.nohover{
    transition:.3s;
    position:absolute;
}
.nohover{
    opacity:0;
}
a:hover .hover{
    opacity:0;
}
a:hover .nohover{
    opacity:1;
}body {
  background-color: grey;
  background: url(http://wizzfree.com/pix/bg1.jpg) fixed;
  background-size: 100% 100%;
  background-repeat: no-repeat;
  overflow: hidden;
  margin: 0px;
  font-family: Arial;
  color: darkgrey;
  font-size: 12px;
  line-height: .3;
  letter-spacing: .5px;
}
.call {
    position: fixed;
    top: 180px;
    left: 50%;
    width: 150px;
    height:123px;
    transform:translateX(-50%); /* center */
    z-index: 3;
}

.hover,.nohover{
    transition:.3s;
    position:absolute;
}
.nohover{
    opacity:0;
}
a:hover .hover{
    opacity:0;
}
a:hover .nohover{
    opacity:1;
}
<div class="call">
  <a href="startchat.htm">
  <img src="http://wizzfree.com/pix/call2.png" width="150" class="nohover">
  <img src="http://wizzfree.com/pix/call3.png" width="150" class="hover"></a>
