我使用 HTML/CSS 设计我的个人网站。但文字并没有缩放到手机上。请参考下面的图片。
桌面上的网站看起来很棒，但在移动设备上显示效果不佳。
手机显示
我的谷歌驱动器嵌入甚至不适合手机屏幕显示。 手机显示 GGD PDF 嵌入
我应该怎么做才能解决这个问题？非常感谢。
下面是我的代码：

您的网站未按预期在移动设备上显示的原因是您需要更多媒体查询来根据尺寸指定布局和设计。您有一个媒体查询。使用以下媒体查询更改浏览器的大小，并使用代码，使其类似于您的预期结果：
/* Media Queries */ @media (min-width:320px) { /* Vertical Screen Phones */ } @media (min-width:480px) { /* Horizontal/Landscape Screen Phones */ } @media (min-width:600px) { /* Tablets and Vertical iPads */ } @media (min-width:801px) { /* Tablet, Horizontal/Landscape iPads, low-resolution Laptops */ } @media (min-width:1025px) { /* Big Tablets */ } @media (min-width:1281px) { /* Laptops and Desktops */ }此外，我建议坚持使用 rem 或 em 而不是 vh。它的使用更广泛，并且更具可扩展性。
