私のウェブページはYouTubeの再生リストを再生し、トラックの名前を一番下に表示します（その日の大半を費やしています）、サムネイルをプレイリストから再生している特定のビデオがトラックタイトルの最下部に表示されます。私は特定のビデオでこれを行う方法を理解していますが、これをビデオの再生リストにどのように実装しますか？再生される新しい曲ごとにイメージがリフレッシュされることが重要です。 https://jsfiddle.net/ruumL5s7/YouTubeを抽出するサムネイルを再生リスト内の動画から表示するとウェブページ上に表示
も、私は垂直方向に映像を合わせ、上部と下部のバーの間にdivをチャットで問題が生じています：ここで
は私の現在の仕事にjsfiddleです。私はまた、画面がリサイズされたときに、（完全な）バーを残さずに、下のバーに問題を抱えています。別のdivがすべて分断されています。だから、どんな支援も大歓迎です！ありがとうございました！
