わかりました、少し問題があります。このサイトで答えを探すのに約3時間費やしました。css ファイルがあり、SVG 画像を背景に配置しようとしていますが、background-size: 75px 75px;機能しません。私はこれらの両方を使用しようとしましたが、動作しません:
section.main .content { margin: 15px; background: no-repeat centre top/75px 75px no-repeat; padding-top: 85px; }
section.main .content { margin: 15px; background: no-repeat centre top; background-size: 75px 75px no-repeat; padding-top: 85px; }
プログラマーのメモ帳では単語background-sizeは赤で、Web ページでは次のようになっているはずですが、次の
結果が得られています。
ここに私の完全なコードがあります:
