CSSMediaRule.media
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since 2015年7月.
media は CSSMediaRule インターフェイスの読み取り専用プロパティで、 MediaList でスタイル情報の出力先メディアを表します。
値
MediaList です。
例
この CSS には、単一のスタイルルールを持つメディアクエリーが含まれています。これは document.styleSheets[0].cssRules が返す最初の CSSRule になります。
したがって、 myRules[0].media を呼び出すと、メディアクエリーを表す MediaList オブジェクトを返します。
css
@media (min-width: 500px) {
body {
color: blue;
}
}
js
let myRules = document.styleSheets[0].cssRules;
console.log(myRules[0].media); // a MediaList
