CSS Media Features - Orientation

Previous
Quiz

CSS orientation media feature is used to determine whether the device's screen or page is in a portrait or landscape orientation.

The orientation of the device is not always the same as the orientation of the screen. For example, if you open the soft keyboard on a device in portrait orientation, the screen will become wider than it is tall. In this case, the browser will use landscape styles instead of portrait styles.

Possible Values

  • portrait − This value is applied when the height of the viewport exceeds its width, which commonly indicates that a device is held vertically.

  • landscape − This value is applied when the width of the viewport is greater than its height, typically indicating that the device is held in a horizontal orientation.

Syntax

 orientation: portrait|landscape;

CSS orientation - landscape Value

The following example demonstrates that when the device is in landscape orientation, the background color of the box changes to the yellow −
