要完成此效果把如下代码加入到区域中
<script language="javascript">
//显示的信息，可以使用HTML语法，注意引号用法，单套双
var message='
WELCOME TO TYPHOON START'
//背景色
var backgroundcolor="#ffffff"
//0 代表信息永远显示，1 代表信息只显示一段时间，2为随机显示模式；
var displaymode=1
//如果显示模式为在指定时间内显示，输入时间段(1000为1秒)；
var displayduration=10000
//1代表闪烁，0代表不闪烁；
var flashmode=0
//如果设置了闪烁，输入闪烁的颜色；
var flashtocolor="lightgreen"
////下面不必修改///
