从mysql加载的样式数据

Question

我有一个用户可以添加联系人的列表。一个数字列表。每次添加记录编号时，我都希望通过css transiton将fade添加到列表中。

我写了这段代码：

while($record=mysql_fetch_array($selectResult))
    {
        $cont++;
        if($record["T_id"]!=""){
            //echo $record["T_id"]." - ".$record[1]." - ".$record[2]."<br>";
            echo '<div class="numRecord" id="Numrecord-'.$cont.'" style="opacity:1">
                  <p class="recordCont">'.$cont.' -</p>
                  <p class="recordName">'.$record["T_name"].'</p>
                  <p class="recordNum">'.$record["T_prenumber"].'-'.$record["T_number"].'</p>
                  <a href="edit.php?edit=edit" id="edit-'.$cont.'">Edit</a>
                  <a href="edit.php?edit=del&&id='.$record["T_id"].'" id="delet-'.$record["T_id"].'">Delete</a>
              </div>';

        }else{
            echo "Nothing to show"; 
        }
    }

和css是：

.numRecord {
    position:relative;
    border:1px dotted rgba(0,0,0,0.63); 
    width:100%;
    height:30px;
    float:left;
    margin:5px 0 5px 0;
    -webkit-transition:1s all ease;
    -moz-transition:1s all ease;
    -o-transition:1s all ease;
    -ms-transition:1s all ease;
    transition:1s all ease;
    opacity:0;
}

但过渡不起作用:( ...
