Question

目前我的导航栏高约50px。我希望它大约是150px。我尝试通过在CSS文件中编写我自己的创建添加到Bootstrap的导航栏类，但更改导航栏，导航或其他任何内容的高度似乎不会影响布局。如何更改导航栏高度？还有，字体颜色？

.navbar-inverse {
	background-color: #337ab7;
	border-color:#337ab7;
	border-radius: 0px;
	height:100px;
	width:100%;
	position: fixed;
}

.navbar-inverse .navbar-nav>.open>a, .navbar-inverse .navbar-nav>.open>a:hover, .navbar-inverse .navbar-nav>.open>a:focus {
	color: #fff;
	background-color: #0e364c;
}

.navbar-inverse .navbar-nav>li>a {
	color:#ffffff;font-family: 
	'Open Sans', sans-serif;
}
.navbar-inverse .navbar-brand { 
	color:#ffffff;
}
.menu { 
	display:none;
}


@media all and (max-width:768px){

/*login register*/

@import url(http://fonts.googleapis.com/css?family=Roboto);

Answer 1

您可以按照自己的方式进行编辑，只需确保在引导程序文件之后加载了css文件。不是之前，这就是它的样子。

这是基于假设这是你的css文件：

  <link type = "text/css" rel = "stylesheet" href= "{% static 'polls/stylesheet.css' %}" />

如果你交换这两个，它应该覆盖bootstraps设置：

  <link type = "text/css" rel = "stylesheet" href= "{% static 'polls/stylesheet.css' %}" />
  <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous">

Answer 2

首先，您需要重新排列样式表。引导程序必须是第一个，并且您的自定义css文件必须在Bootstrap之后才能覆盖它。

这是正确的顺序：

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous">
<link type = "text/css" rel = "stylesheet" href= "{% static 'polls/stylesheet.css' %}" />

现在，为了覆盖导航栏的高度，在自定义样式表中更改.navbar类的最小高度

.navbar {
    min-height: 150px;
}

并且对于颜色，您需要以下覆盖：

.navbar-inverse .navbar-nav > li > a {
    color: red; /* here goes the color of your choice */
}

Answer 3

如果bootstrap覆盖了你的CSS属性，那么你必须为你定义的CSS属性指定！important ，比如

.navbar{
   height:150px !important;
}

Answer 4

对于自定义高度，您必须使用！在定义身高时很重要。

.navbar {
   min-height: 150px !important;
}
