device-aspect-ratio CSS media feature

Deprecated

Avoid using this feature in new projects. Device media queries do not reflect available layout, only the physical size of the device. This feature may be a candidate for removal from web standards or browsers.

Consider using the following features instead: Media queries.

Note: To query for the aspect ratio of the viewport, developers should use the aspect-ratio media feature instead.

The device-aspect-ratio CSS media feature can be used to test the width-to-height aspect ratio of an output device.

Syntax

The device-aspect-ratio feature is specified as a <ratio>. It is a range feature, meaning that you can also use the prefixed min-device-aspect-ratio and max-device-aspect-ratio variants to query minimum and maximum values, respectively.

Examples

article {
  padding: 1rem;
}

  article {
    padding: 1rem 5vw;
  }
