1、无论屏幕放大缩小，悬浮广告一直在右侧html代码布局
<div class="wd_page">
<div class="scrop_top_fr">
<ul class="scrop_top_con">
<li><a href="#activity_name_270">套装1.8折起</a></li>
<li><a href="#activity_name_269">脱“光”必备</a></li>
<li><a href="#activity_name_272">闪购新品</a></li>
</ul>
</div>
</div>
2、css结构
wd_page {
overflow: hidden;
position: relative;
width: 100%;
}
.scrop_top_fr {
margin-right: -620px;
margin-top: -250px;
position: fixed;
right: 50%;
top: 50%;
z-index: 99999;
}
