我使用 HTML/CSS 設計我的個人網站。但文字並沒有縮放到手機上。請參考下面的圖。
桌面上的網站看起來很棒，但在行動裝置上顯示效果不佳。
手機顯示
我的Google驅動器嵌入甚至不適合手機螢幕顯示。 手機顯示 GGD PDF 嵌入
我該怎麼做才能解決這個問題？非常感謝。
下面是我的程式碼：

您的網站未如預期在行動裝置上顯示的原因是您需要更多媒體查詢來根據尺寸指定佈局和設計。您有一個媒體查詢。使用以下媒體查詢更改瀏覽器的大小，並使用程式碼，使其類似於您的預期結果：
/* 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，我建議堅持使用 rem 或 em 而不是 vh。它的使用更廣泛，並且更具可擴展性。
