首先我们需要一个html代码的框架如下：
<div style="position: absolute; top: 0px; left: 168px; width: 100%; margin-left: auto; margin-right: auto; height: 47px; border: 0px solid red; overflow: hidden;">
<ul id="syNoticeUlNew" style="margin: 0px;left:0; top:0;margin-bottom:0px;width:100%;height:47px;position:absolute;">
</ul>
</div><div style="position
