消除引导程序导航栏和内容之间的差距

问题描述 投票：-1回答：2

我的本地css样式表中的.navbarstyle不会覆盖bootstrap预定义的一个。

尝试更改导航栏颜色并消除它与内容之间的差距，似乎无法做到这一点。

我把本地css文件放在head标签内的bootstrap下面，并修复了我的字体覆盖问题，但它似乎没有让我改变其他东西。

height: 100%;
background-position: center;
background-repeat: no-repeat;
background-size: cover;
color: #FFF;

/*    Center text vertically in background image*/
display: flex;
flex-direction: column;
justify-content: center;

您必须使用比框架使用的更具体的选择器。例如。对于.navbar使用nav.navbar

编辑：在你的情况下，.bg-dark类覆盖红色背景，从这里删除它：

<nav class="navbar navbar-expand-md navbar-dark bg-dark fixed-top">

至

<nav class="navbar navbar-expand-md navbar-dark fixed-top">

见下文：

nav.navbar {
  margin-bottom: 0;
  background-color: red;
  font-size: 1.4em;
  font-family: 'Pinyon Script', cursive;
}
<head>
  <meta charset="utf-8">

尝试在bootstrap.css之后导入你的css样式文件！

  <link href="css/bootstrap.min.css" rel="stylesheet">
  <link href="css/your.css" rel="stylesheet">
