为解决这个问题付出了太多努力:
我的导航菜单包含"a href="#project" project /a"
,其中包含另一个 section
。我想要 "project"
来改变颜色
#project 是定位的。
我做的非常简单的方法是li a:focus {color:red;}
。它的工作原理但必须点击两次。有没有办法让这个焦点只需点击一下就可以了?
li a:focus{
padding-top: 5px;
max-height: 50px;
opacity: 1;
color:red;
}
#project{
opacity: 0;
transition: opacity 0.5s ease;
}
#project:target{
opacity: 1;
}
<body>
<nav> <img class="nav_bar" src="images/navigation_stick.png">
<ul class="subsection">
<li class="subsection"><a class="none" href="#none">Animation</a>
<a href="#project" class="subsection">Project</a>
</li>
<li>
<h2>Animation</h2>
<p>We have created a world-class</p>
</li>
</ul>
</nav>
<section id="project">
<div class="container">
<div>
<div class="list">
<img class="back" src="images/.jpg">
<article class="details">
<h2 class="details">Windows Civilization</h2>
<p class="details">A projection of civilization</p>
<a href="" class="button"><span class="butt">See Project</span></a>
</article>
</div>
</div>
</div>
</section>
</body>

如果你不喜欢使用一点Javascript,你可以使用一个简单的类更改函数来实现相同的功能。
$('nav a').click(function(){
if ($(this).hasClass('project')) {
$(this).addClass('active');
} else {
$('.project').removeClass('active');
}
});
你可以在这里看到一个工作小提琴:http://jsfiddle.net/JHLN4/48/
请注意,我必须将您的CSS规则从li a:focus
调整为li a:focus, li a.active
,以确保它适应新课程。我还在HTML结构中添加了一个类project
,以便在单击另一个a
标记时更轻松地删除该类。
查看下面的完整结构(neatened):
$('nav a').click(function() {
if ($(this).hasClass('project')) {
$(this).addClass('active');
} else {
$('.project').removeClass('active');
}
});
li a:focus,
li a.active {
padding-top: 5px;
max-height: 50px;
opacity: 1;
color: red;
}
#project {
opacity: 0;
transition: opacity 0.5s ease;
}
#project:target {
opacity: 1;
}
