Question

我的css文件有问题。这些样式没有应用于iPhone，而是我获得了适用于iPhone和iPad的iPad查询。我检查并检查了拼写错误，但找不到任何错误。这是我的iPad和iPhone查询的css文件：

我没有看到任何明显的错别字或错误会阻止代码运行。为什么媒体查询不起作用？任何帮助赞赏。谢谢。

Answer 1

这可能是因为没有设置视口：https://www.w3schools.com/css/css_rwd_viewport.asp至少我的代码中没有看到任何视口。

也;我总是学习每个screentype有单独的样式表;它更容易维护，移动用户不必拉入不必要的IPad css。

为此，我将媒体查询放在head标签和视口之间。每个媒体查询都链接到单独的.css文件

以下是使用两种样式的HTML文件的示例。我相信你可以使用'和'来扩展媒体查询，这将允许你在最小和最大之间使用特定的样式表进行屏幕大小。

<!DOCTYPE html>
<html lang="en">
    <head>
        <meta charset="UTF-8">
        <title>demo</title>
        <link rel="stylesheet" href="reset.css" type="text/css">    <!-- My CSS reset -->
        <link rel="stylesheet" href="style.css" type="text/css">    <!-- My main style, also for PC... -->
        <link rel="stylesheet" type="text/css" media="only screen and (max-device-width: 480px)" href="mobile_style.css" />    <!-- Mediaquery that detects mobile screens and serves them the other stylesheet-->
        <meta name="viewport" content="width=device-width, initial-scale=1.0, user-scalable=no">    <!-- viewport -->
    </head>
    <body>
        <p>Responsive text goes here.</p>
    </body>
</html>
