css中的媒体查询无效

时间：2016-09-17 15:41:37

标签： html css media

我在索引页面上实现媒体查询时遇到了一些问题。

当我在浏览器中调整页面大小时，即使在不同的媒体查询中指定了它们，我仍然会获得移动版和桌面版。

我的手机版似乎没有任何样式：/

有人在这看到我的错吗？

1 个答案:

答案 0 :(得分：1)

以下是基于每个媒体查询隐藏/显示每个div的示例。

我添加了这两个规则，每个查询一个

#contentmobile {
    display: none;
}

#content {
    display: none;
}

此外，*//个字符会弄乱你的CSS，而不是使用/* comment */ 

@charset "utf-8";

@font-face {
    font-family: sinhala;
    src: url(fonts/Sinhala.ttc);
}

*{
	padding: 0%;
	margin: 0%;
	box-sizing: border-box;
	
}
