我有以下代码在firefox中正常工作，但是当我想从移动设备上看它时，它会削减我的一些div标签的结尾。他们根本没有表现出来。我错过了什么吗？请参阅以下内容：
<div class="banner-bg">

这是我的相关CSS。如果有必要展示我的CSS的其他部分，请告诉我：
.banner-bg {
position: relative;
}
.banner {
position: absolute;
top: 0;
width: 80%;
margin: 0 auto;
right: 10%;
}
答案 0 :(得分：0)
正如您已经写过的<div class="online_reservation">根本没有显示。因此，如果上述规则包含在@media查询样式规则中，则必须签入样式表文件。
例如：
@media only screen and (max-width: 500px) {
.online_reservation {
display:none;
}
或者至少你必须提供一个CSS文件的链接，这样我就可以看看并给你一个更准确的答案。
