我正在尝试在bootstrap中创建导航栏。在bootstrap-theme.min.css文件中添加了自定义样式。通过这种方式,我可以创建导航栏,但是下拉菜单项会隐藏在小屏幕设备的主菜单后面。输出的代码和截图如下:
在bootstrap-theme.min.css文件中添加样式:
#custom-bootstrap-menu.navbar-default .navbar-brand {
color: rgba(255, 255, 255, 1);
}
#custom-bootstrap-menu.navbar-default {
font-size: 14px;
background-image:url('https://s3.amazonaws.com/static.bizmerlin.net/bg_header.png');
background-repeat:repeat-x;
background-size:100% 100%;
border-width: 1px;
border-radius: 4px;
height: 40px;
background-color: rgba(70, 131, 176, 1);
}
#custom-bootstrap-menu.navbar-default .navbar-nav>li, .navbar-brand {
color: rgba(255, 255, 255, 1);
background-color: #528cb4;
height: 38px;
border: 1px solid #ffffff;
margin-top:4px;
border-radius: 5px;
margin-right: 6px;
font-size: 14px;
}
#custom-bootstrap-menu.navbar-default .navbar-nav>li>a, .navbar-brand {
color: rgba(255, 255, 255, 1);
line-height: 10px;
}
#custom-bootstrap-menu.navbar-default .navbar-nav>li:hover,
#custom-bootstrap-menu.navbar-default .navbar-nav>li:focus {
background-color: #7fbb00;
}
#custom-bootstrap-menu.navbar-default .navbar-nav>li.active>a,
#custom-bootstrap-menu.navbar-default .navbar-nav>.active>a:hover,
#custom-bootstrap-menu.navbar-default .navbar-nav>.active>a:focus {
color: rgba(255, 255, 255, 1);
background-color: rgba(233, 129, 42, 1);
}
#custom-bootstrap-menu.navbar-default .navbar-toggle {
border-color: #e9812a;
}
#custom-bootstrap-menu.navbar-default .navbar-toggle:hover,
#custom-bootstrap-menu.navbar-default .navbar-toggle:focus {
background-color: #e9812a;
}
#custom-bootstrap-menu.navbar-default .navbar-toggle .icon-bar {
background-color: #e9812a;
}
#custom-bootstrap-menu.navbar-default .navbar-toggle:hover .icon-bar,
#custom-bootstrap-menu.navbar-default .navbar-toggle:focus .icon-bar {
background-color: #4683b0;
}
#custom-bootstrap-menu.navbar-default .navbar-nav > li > .dropdown-menu {
background-color: #528cb4;
margin-top:10px;
}
#custom-bootstrap-menu.navbar-default .navbar-nav > li > .dropdown-menu > li > a {
color: #ffffff;
}
#custom-bootstrap-menu.navbar-default .navbar-nav > li > .dropdown-menu > li > a:hover,
#custom-bootstrap-menu.navbar-default .navbar-nav > li > .dropdown-menu > li > a:focus {
color: #aeff00;
background-image: none;
background-color: #528cb4;
}
#custom-bootstrap-menu.navbar-default .navbar-nav > .open > a {
background-image: none;
background-color: #7fbb00;
height: 36px;
border-radius: 4px;
}
.caret {
border-left: 4px solid transparent;
border-right: 4px solid transparent;
border-top: 4px solid;
display: inline-block;
height: 0;
margin-left: 2px;
vertical-align: middle;
width: 0;
}
导航栏的HTML代码是:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Bootstrap 3 Responsive Layout Example</title>
<link rel="stylesheet" type="text/css" href="css/bootstrap.min.css">

<div class="collapse navbar-collapse navbar-menubuilder" >

<li><a href="/about-us">About Us</a>
</li>
<li><a href="/contact">Contact Us</a>
</li>
<li class="dropdown">
<a class="dropdown-toggle" data-toggle="dropdown" href="#" aria-expanded="false">Page 1 <span class="caret"></span></a>
<ul class="dropdown-menu" >
<li><a href="#">Page 1-1</a></li>
<li><a href="#">Page 1-2</a>
<ul class="dropdown-menu sub-menu">
<li><a href="">asf</a></li>
</ul>
</li>
<li><a href="#">Page 1-3</a></li>
</ul>
</li>
<li><a href="/contact">Contact Us</a>
</li>
</ul>
<ul class="nav navbar-nav navbar-right">
<li><a href="">Analytics</a></li>
</ul>
</div>
</div>
</nav>
<div class="container">
</div>
</body>
</html>
输出为:
下拉菜单隐藏在Contactus和Anlytics背后。请帮我解决这个问题。提前致谢。如果我的问题不明确,请告诉我。

答案 0 :(得分:2)
更新:我已将此添加到您的css
#custom-bootstrap-menu.navbar-default .navbar-brand{
height:38px;
}
并从height:38px;
移除了#custom-bootstrap-menu.navbar-default .navbar-nav>li, .navbar-brand
。这应该可以解决问题。
#custom-bootstrap-menu.navbar-default .navbar-brand {
color: rgba(255, 255, 255, 1);
