Question

我正在bootstrap中创建一个登陆页面，所以我添加了固定的导航栏，我在登录表单的右侧登录表单向导航栏添加更多高度实际上我使用的位置移动到顶部但是高度导航栏没有减少（我也尝试了margin-top和padding-top），我也希望改变导航栏的颜色（我试图通过使用background-color和！important属性来改变导航栏的颜色）我该如何解决这个问题问题

这是我的代码

Answer 1

解决方案是通过css值覆盖来自引导程序的默认css值。

此类导航栏控制导航栏的最小高度和颜色背景颜色，因此更改其CSS属性可以解决您的问题。

我做了这个：

.navbar {background：red;最大高度：50px; }

将上述css放在您的页面中，它将按您的意愿运行。您可以根据需要更改值。

更改Bootstrap导航栏的颜色并降低导航栏的高度
