你把首页里的东西放到一个div层，然后设置
style="position: absolute;z-index: 100"
然后你的下拉广告style='z-index: 999' 这样就好了，
建议你学学CSS里面的position，和z-index属性

图片轮播器之类的，具体原来就是将图片css设置成relativ，wrapper中设置为overflow为隐藏,然后更改左侧或者右侧的位置或者margin的值，上下就是更改上下的值。基本思路就是这个。
具体的演示给你个我最近找的：
定义弹出层代码
div class="advbox"
div class="advpic"
img width="670" height="420" alt="" src="images/xin.jpg"/
a href="javascript:void(0);" class="closebtn"关闭/a
/div
/div
添加css样式
*{margin:0;padding:0;list-style-type:none;}
a,img{border:0;text-decoration:none;}
body{font:12px/180% Arial, Helvetica, sans-serif,"";}
/* advbox */
*html,*html body{background-image:url(about:blank);background-attachment:fixed;}
*html .advbox{position:absolute;top:expression(eval(document.documentElement.scrollTop));}
.advbox{width:670px;position:fixed;display:none;left:50%;top:0;margin:-215px 0 0 -325px;}
.advbox .advpic{position:relative;height:420px;overflow:hidden;}
.advbox .advpic .closebtn{display:block;width:40px;height:20px;line-height:20px;font-size:12px;color:#fff;text-indent:12px;overflow:hidden;position:absolute;right:5px;top:0px;z-index:99;}
加入jq代码
$(document).ready(function(){
var COOKIE_NAME = "showbox";
if($.cookie(COOKIE_NAME)){
$(".advbox").hide();
}else{
$(".advbox").show();
$(".advbox").animate({top:"50%"},1000);
$(".closebtn").click(function(){
$(".advbox").fadeOut(500);
})
$.cookie(COOKIE_NAME,'ishide',{expires:1});
}
})
您好：这个可以直接百度下载一个jquery插件即可。看你的意思就是一个广告图片然后在页面上来回的动，碰到周边就改变方向那个效果吧？百度一大把。
