Jq制作的页面顶部动态弹出的提示框，可以用于提示信息的显示以及通知信息的显示。

Css代码
body {
margin: 0;
padding: 0;
}
.tooltiptop {
width: 100%;
height: 50px;
margin-top:-50px;
display:none;
}
.tooltiptop .bg {
width: 100%;
background-color: #333;
height: 50px;
opacity: .7;
position: absolute;
margin: 0;
}
.tooltiptop .main {
width: 100%;

}
.tooltiptop .main span {
float: right;
color: #fff;

Jq代码
var ToolTipTop={

$(".tooltiptop .main i").html(Msg);
$(".tooltiptop").css("display","block").animate({marginTop:"0px"},500);
