CSS媒体查询(最大高度)不起作用，但为什么？

我有页面-http://pgkweb.ru/temp/1/index.html和它的样式-http://pgkweb.ru/temp/1/include/style.css。对于移动设备，我需要扩大块之间的边距。所以我试着

@media (max-height: 800px)

而且它不工作(背景不是金色)。

如果我这样做

 @media not screen and (max-height: 800px)

我电脑上的背景更改。是否可以使其正常工作？

解决方案

您的HTML页面具有<meta name="viewport" content="width=device-width, initial-scale=0.6"> 它应该显示 <meta name="viewport" content="width=device-width, initial-scale=1.0">

将所有这些代码添加到现有CSS表的末尾
