我正在尝试使用响应式css来处理媒体查询的某些问题。问题是移动屏幕没有向下滚动，分辨率为320x480。任何想法为什么它不向下滚动？
最诚挚的问候。

@media only screen and (max-device-width: 320px) and (max-device-height:480px) and (orientation: portrait) {

.logo {

EdiT 1：您可以在www.ioterm.com上查看不使用预定义的320x480分辨率的其他版本。在@media only屏幕下有此代码，（max-width：767px）
html, body {
overflow-y: auto !important;
}
如果我禁用它滚动不起作用。但是如果我将它添加到320x480媒体查询中，它仍然无法正常工作。
答案 0 :(得分：0)
添加此代码可以使其正常工作！
