orientation
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
CSS 媒体属性屏幕方向(orientation
)可用于测试视口 viewport(或者对于分页媒体而言的页面框盒)的横纵方向。
备注:此属性不等价于设备的屏幕旋转方向。在许多设备上,当屏幕方向为纵向时,打开软键盘将导致视口 viewport 的宽度大于高度,从而导致浏览器突然改用横向样式,而不是保持纵向。
