小さなスクリーン/モバイルデバイスで問題が発生する純粋なCSSメニューがあります。純粋なCSSメニューが開いているときにボディスクロールを防止し、デバイスの高さを超えてメニューをスクロールできるようにします。
問題1 メニューを開いても、背景はスクロール可能です。フォーカスがメニューにあるようにしたいので、メニューが開いているときに背景がスクロールしません。
問題2 小さな画面では、メニュー項目がデフォルトで折りたたまれ、クリックするとサブメニューが表示されます。 1つまたは2つが展開され、コンテンツがデバイスウィンドウを超えた場合、スクロールして現在のウィンドウビューの外にあるコンテンツを表示する方法はありません。メニューが展開されている場合は、スクロール可能である必要があります。
オーバーフロープロパティを試しましたが、問題を解決できません。誰かがどのように知っていることを願っありがとう！
