StyleSheet: media property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since September 2015.

The media property of the StyleSheet interface specifies the intended destination media for style information. It is a read-only, array-like MediaList object and can be removed with deleteMedium() and added with appendMedium().

Value
