/*在这段下面添加代码*/

然后在下方添加以下代码

<!--网站访问量-->

/*在这段下面添加代码*/

然后在这两行任意位置添加以下信息，推荐是在版权信息下添加。

<p id="time">Tonm's Blog 的站点正在加载数据.....</p>

然后打开后台-外观-外观设置-自定义设置-复制代码粘贴至底部自定义内容

<!--底部运行时间-->
<script  type="text/javascript">
    var colorStr="";

    var now =new Date(); 
    function StorageTime() {

</script>
<!--运行时间-->

然后再去自定义Css样式添加以下代码即可

/*运行时间字体美化*/
    #time{
        text-shadow: 0px 0px 3px blue;
        text-align: center;
    }
    #time span{
        color: red;
        padding: 0 8px;
    }
