The orientation CSS media feature can be used to test the orientation of the viewport (or the page box, for paged media).

Note: This feature does not correspond to device orientation. Opening the soft keyboard on many devices in portrait orientation will cause the viewport to become wider than it is tall, thereby causing the browser to use landscape styles instead of portrait.

Syntax

The orientation feature is specified as a keyword value chosen from the list below.

Keyword values

portrait
The viewport is in a portrait orientation, i.e.,  the height is greater than or equal to the width.
landscape
The viewport is in a landscape orientation, i.e., the width is greater than the height.

Example

HTML

<div>Box 1</div>
<div>Box 2</div>
<div>Box 3</div>

CSS

body {
  display: flex;
}

div {
  background: yellow;
}

@media (orientation: landscape) {
  body {
    flex-direction: row;
  }
}

@media (orientation: portrait) {
  body {
    flex-direction: column;
  }
}
