更改Bootstrap導航欄的顏色並減小導航欄的高度

Question

我正在引導程序中創建登錄頁面，因此我在其中添加了固定的導航欄，其中右側有登錄表單，登錄表單為導航欄增加了更多的高度，實際上我使用了位置移動到頂部，但導航欄的高度不是減少（我也嘗試過margin-top和padding-top），並且我想更改導航欄的顏色（我嘗試通過使用background-color和！important屬性更改導航欄的顏色）如何解決此問題

這是我的代碼

解決方案是用css值覆蓋來自引導程序的默認css值。

這里的navbar類控制着導航欄的最小高度和彩色背景色，因此更改其CSS屬性可以解決您的問題。

我已經完成了這一步：

.navbar {背景：紅色； max-height：50像素； }

將上面的CSS放在您的頁面中，它將根據您的需要工作。您可以根據需要更改值。
