css 透明效果 div

定义1:
.div_transparent, .div_time, .div_rpt_now, . div_suggestion,. div_ap_item
{
    text-align: center;
    filter:alpha(opacity=100); /* IE */ -moz-opacity:1.0; /* Moz + FF */
    opacity: 1.0; 
    background:#ccc; 
}

.div_ap_item
{
   top: 10px;
    left: 5px;
    height: 80px;
    width: 90px;
    line-height: 20px;
    font-size: small;
    color: #006600;
    font-family: 微软雅黑;
    text-align: center;
}

定义2:
.div_ap_item
{
    text-align: center;
    filter:alpha(opacity=100); /* IE */ -moz-opacity:1.0; /* Moz + FF */
    opacity: 1.0; 
    background:#ccc; 
}

.div_ap_item
{
   top: 10px;
    left: 5px;
    height: 80px;
    width: 90px;
    line-height: 20px;
    font-size: small;
    color: #006600;
    font-family: 微软雅黑;
    text-align: center;
}

我一直认为这两种定义方式的效果应该是一样的,奇怪的是,定义1可以产生透明效果;定义2却没有
怎么回事呢?

回复讨论(解决方案)

.div_transparent, .div_time, .div_rpt_now, . div_suggestion, . div_ap_item

注意空格

.div_transparent, .div_time, .div_rpt_now,  .div_suggestion,  .div_ap_item

大哥
你的定义1里面“. div_ap_item”明显有个空格啊
