推荐答案

您可能在html头中缺少 viewport元标记:

You are probably missing the viewport meta tag in the html head:

视口是用户在网页上的可见区域.您需要使用 width = device-width 将宽度设置为要在移动设备，平板电脑或台式机中查看的设备宽度.

Viewport is the user's visible area of a web page. Using width=device-width you need to set the width to device width you are viewing in like mobile or tablet or desktop.

<meta name="viewport" content="width=device-width, initial-scale=1">
