我在我的網站中采用了 Bootstrap 5 固定導航欄示例，但經過數小時的研究，我仍然無法洗掉底部的空白區域。請參閱 Bootstrap 5 鏈接，并注意卡片下方的底部空白區域。 https://getbootstrap.com/docs/5.1/examples/navbar-fixed/
每當頁面“簡短”時，我的網站都有相同的空白，而對于長頁面，它顯然不會出現。
我嘗試通過我的自定義 css 檔案覆寫以下內容，但這沒有產生任何結果。我知道這張表確實會被拿走，因為我正在使用其他東西。
html, body, footer {
padding-bottom: 0px !important;
margin-bottom: 0px !important;
}
footer.well{
margin-bottom: -20px !important;
}
任何人都可以請說明我如何洗掉這個空白區域嗎？
這是來自上述網站的代碼：

uj5u.com熱心網友回復：
如果您剛剛完整復制了您鏈接到的示例站點，則該站點有一個名為“navbar-top-fixed.css”的樣式表，其規則如下
body {
min-height: 75rem;
padding-top: 4.5rem;
}
如您所見，它的最小高度規則為 75rem。它旨在通過強制內容非常高來展示當內容溢位時導航欄粘在頂部的事實。這并不打算在實際代碼中使用。如果您已將該樣式表復制到您的網站上，則只需洗掉最小高度規則（如果您想要導航欄，填充規則仍然很重要，因為這會阻止內容出現在您的導航欄下方）
