私はStackOverflowの中で検索し、誰かがCodeplyでこの機能を使用することを発見し、here’s the link、そしてそれだけで正常に動作します。
コードを取ってCodepenに入れましたが、動作させることができませんでした：here’s the link。これがHTMLです。

そして、これはCSSです。
body {
position: relative;
overflow-y: auto;
padding-top: 70px; /* padding for fixed navbar */
}
Codepenでスクロールすると、ナビゲーション項目は変更されませんが、Codeplyでは変更されます。
は誰が悪いのか知っていますか？
ご協力いただきありがとうございます。
Juan Betancourt。
PS：私はそれは問題がCSSとJavaScriptペンの設定やbodyタグの属性であることも可能だと思います。
