你好我是html和CSS的新手,我正在使用bootstrap来创建一个网站。我想改变右侧导航栏上活动按钮的颜色。还想在我看到一些例子时改变文本颜色,但我无法将其应用于此示例。提前致谢。
HTML:
<div class="Menu">
<nav class="navbar navbar-inverse navbar-static-top">
<div class="container">
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data- toggle="collapse" data-target="#navbar">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-left" href="http://www.website.com"> <img src="Logo.png" alt="LOGO">
</a>
</div>
<div id="navbar3" class="navbar-collapse collapse">
<ul class="nav navbar-nav navbar-right">
<li class="active"><a href="#">Home</a></li>
<li><a href="#">About</a></li>
<li><a href="#">Contact</a></li>
<li class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false">Dropdown <span class="caret"></span></a>
<ul class="dropdown-menu" role="menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li class="divider"></li>
<li class="dropdown-header">Nav header</li>
<li><a href="#">Separated link</a></li>
<li><a href="#">One more separated link</a></li>
</ul>
</li>
</ul>
</div>
<!--/.nav-collapse -->
</div>
<!--/.container-fluid -->
</nav>
</div>
CSS:
navbar-right{
padding-top: 35px;
}
img {
padding-top: 17px;
padding-left: 17px;
}
.jumbotron {
padding-top: 10px;
padding-bottom: 48px;
border: 2px solid black;
}
.navbar-inverse .navbar-nav > li > a {
color: green;
}
.navbar3 > .navbar-nav .navbar-right>.active {
color:red;
background-color:yellow;
}
.navbar3 > .navbar-nav .navbar-right>.active > a,
.navbar3 > .navbar-nav .navbar-right>.active > a:hover,
.navbar3 > .navbar-nav .navbar-right>.active > a:focus{
color:red;
background:blue;
}

尝试使用此css来超越Bootstrap css规则:
.navbar-inverse .navbar-nav>.active>a{
background-color:red
}
.navbar-inverse .navbar-nav>li>a:focus, .navbar-inverse .navbar-nav>li>a:hover{
color:red
}
#navbar3 .navbar-nav>.open>a, #navbar3 .navbar-nav>.open>a:focus, #navbar3 .navbar-nav>.open>a:hover{
background-color:red
}

修复后你的css会有一些错误:
.navbar3
,而class
不是id
所以您应该使用#navbar3
.navbar-nav
和.navbar-right
之间也有空格但不应该是空格.navbar-nav.navbar-right
而不是.navbar-nav .navbar-right
所以你的CSS必须是这样的:
#navbar3 > .navbar-nav.navbar-right>.active > a,
#navbar3 > .navbar-nav.navbar-right>.active > a:hover,
#navbar3 > .navbar-nav.navbar-right>.active > a:focus{
color:red;
background:blue;
}
这将更改活动按钮,更改悬停,您应该这样做:
#navbar3 > .navbar-nav.navbar-right>li>a:hover{
color:yellow;
}
