表示されているデバイスに応じて、ヘッダー画像をシームレスに切り替え/置換できるように取り組んでいます。
以前は、max-width、min-width などを使用してサイズを変更するコードを使用していました...
モバイル (最大 400px) またはデスクトップ (最小 480) に応じて、2 つの画像間で交換したい
デスクトップ ヘッダー: ...phl-headline2.jpg
モバイル ヘッダー (交換予定): ...phl-headline-320-2.jpg
ここに私が取り組んでいるコードがあります...
私が持っているものが現在機能していない理由について、誰かが何らかの洞察や答えを持っていることを願っています。
ありがとうございました！
