const firstStyleSheet = document.styleSheets[0]; // the document's first stylesheet
const mediaList = firstStyleSheet.media; // the mediaList of the stylesheet
// set the `media` text to a media query value
mediaList.mediaText = "SCREEN AND (140PX <= WIDTH <= 380PX)";
// add a second media value
mediaList.appendMedium(
"SCREEN AND (MAX-HEIGHT: 400PX) AND (ORIENTATION: LANDSCAPE))",
);
// erroneously, add the same media query again
mediaList.appendMedium(
"SCREEN AND (MAX-HEIGHT: 400PX) AND (ORIENTATION: LANDSCAPE))",
