【问题描述】:
我一直在为网站制作平滑滚动导航栏。我已经设法让导航栏滚动到 HTML 文档中的不同部分,并且我一直试图让导航栏链接根据您所在的网页部分变为活动状态。
在玩弄了代码之后,我不知道该怎么做。我需要做什么?
这是我的代码:
$('#navbar li').click(function() {
$(this).addClass('active').siblings('li').removeClass('active');
});
@import url(https://fonts.googleapis.com/css?family=Maven+Pro:400,900,700,500);
html{
font-family: 'Maven Pro', sans-serif;
}
body{
background:fixed
url(images/bright_squares.png) #cccccc;
position:relative;
padding:0;
margin:0;
}
#home {padding-top:50px;height:500px;color: #fff; background-image:url(images/random_grey_variations.png);}
#about {padding-top:50px;height:500px;color: #fff;}
#portfolio {padding-top:50px;height:500px;color: #fff;}
#contact {padding-top:50px;height:500px;color: #fff;}
background-dark{
background:fixed
url(images/random_grey_variations.png);
}
#navbar {
position:fixed;
top: 0px;
left: 0px;
right: 0px;
height: 60px;
margin: 0;
padding: 0;
list-style: none;
background: #222;
font-family: 'Maven Pro', sans-serif;
font-size: 18px;
font-weight: 300;
}
#navbar li {
position: relative;
float: left;
line-height: 60px;
background: inherit;
text-align: center;
transition: all .2s;
}
#navbar li a {
position: relative;
display: block;
padding: 0 20px;
line-height: inherit;
color: white;
text-decoration: none;
}
#navbar li:before {
content: '';
display: block;
position: absolute;
left: 50%;
margin-left: -30px;
width: 60px;
height: 60px;
background: #222;
border-radius: 50%;
transform: rotate(45deg);
transition: all 0, background .2s;
}
#navbar li:hover:before {
margin-top: 1px;
border-radius: 50% 50% 0 50%;
transition: all .1s, background .2s, margin-top .2s cubic-bezier(.5,30,.2,0);
}
#navbar li:hover,
#navbar li:hover:before {
background: #3a3a3a;
}
#navbar li.active,
#navbar li.active:before {
background: steelblue;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<ul id="navbar">
<li class="active"><a href="#">Home</a></li>
<li><a href="#about">About</a></li>
<li><a href="#portfolio">Portfolio</a></li>
<li><a href="#contact">Contact</a></li>
</ul>
<div id="home">
<h1>Welcome</h1>
<p>Test</p>

<div id="portfolio">
<h1>portfolio</h1>
<p>Test</p>

<div id="contact">

您想要实现的究竟是什么?将箭头保留在蓝色部分的底部?
