    <div class="inner" id="01">
        <a href="#" class="block">
            <span id="s01" class="s01">A</span>
        </a>
    </div>
    <div class="inner" id="02">

            <span id="s02" class="s01">B</span>
        </a>
    </div>
</div>

CSS：

body {

    background-color:navy;
}
#box {
    height: 92px;
    _height: 92px; 
    width: 290px;
    _width: 270px;
    float: left;
    margin-left: 9px;
    margin-top: 48px;
    margin-bottom: 31px;
    margin-right: 26px;
    background-color: #FFF;
    _overflow:hidden;

}
.s01 {
    text-align: center;
    display: block;
    height:100%;
    cursor: pointer;
    padding-top: 36px;
}
.block {
    color:#399;
}

JS：

$(document).ready(function(){


    $("#01").mouseover(function(){$(this).css({
      transition:"all 1s",transform:"scale(1.2)","z-index":"2",
      "background-color":"#24C9C4","border-top":"solid 1px white",
       "border-bottom":"solid 1px white"})})

     $("#01").mouseout(function(){$(this).css({
       transition:"all 1s",transform:"scale(1.0)","z-index":"0",
        "background-color":"#FFF","border-top":"none",
         "border-bottom":"none"})})


     $("#02").mouseover(function(){$(this).css({
      transition:"all 1s",transform:"scale(1.2)","z-index":"2",
      "background-color":"#24C9C4","border-top":"solid 1px white",
       "border-bottom":"solid 1px white"})})

     $("#02").mouseout(function(){$(this).css({
       transition:"all 1s",transform:"scale(1.0)","z-index":"0",
        "background-color":"#FFF","border-top":"none",
         "border-bottom":"none"})})

});

推荐答案

解决这个问题的最简单方法是添加 position：relative 到divs，这将使 z-index 工作。

Probably the neatest way to solve this is to add position:relative to the divs, this will enable z-index to work.

如果不这样做，divs默认为 position：static ，它忽略 z-index ，请参阅：为什么是z -index ignored with position：static？

If you don't do this, the divs are defaulted to position:static which ignores z-index, see: Why is z-index ignored with position:static?

这里有更多的信息，它解释了为什么它在Opera而不是Chrome中工作： http://yagudaev.com/posts/getting-reliable-z-index-cross-browser/

There is more information here, which explains why it works in Opera but not Chrome: http://yagudaev.com/posts/getting-reliable-z-index-cross-browser/

position：absolute 会运作，如果你想使用它，

position:absolute would work as well if you wanted to use that instead, but you would need to specify exactly where you want the divs to be placed.

更新了你的小提琴： http://jsfiddle.net/ua444/1/

您已经在这些div上有一个类，所以唯一的变化是：

You already had a class on those divs so the only change is:

.inner {    
    position: relative;
}
