如何根据主题标签更改活动链接的 CSS

我这里有一个关于如何根据主题标签更改活动链接 css 的情况。 所有内容都在同一页面中，我使用 #url 部分来调用内容。

我已经尝试了几个 javascript 示例和教程，但似乎它不起作用，所以我决定在这里创建一个新问题并与大家分享我的代码。

这是我在浏览器中显示的网址：

file:///Users/FZ/Desktop/HLT/services.html#/mergersandacquisitions
file:///Users/FZ/Desktop/HLT/services.html#/corporatecommercial

这是侧面菜​​单栏的代码：

<!-- Start side menu bar -->
<div id="services_menu">
<ul id="sliding-navigation">
<li class="sliding-element" style="margin-left: 0px;"><h3>Our Services:</h3></li>
<li class="sliding-element" style="margin-left: 0px;"><a href="#capitalmarket">
Capital Market
</a></li>
<li class="sliding-element" style="margin-left: 0px;"><a href="#mergersandacquisitions">
Mergers & Acquisitions
</a></li>
<li class="sliding-element" style="margin-left: 0px;"><a href="#corporatecommercial">
Corporate Commercial
</a></li>
</ul>
</div>
<!-- End side menu bar -->

以下是链接内容的一些示例：

<div class="section">
<h1 style="margin-top: 0.5px;" id="capitalmarket" >Capital Market </h1>
<div id="content_services">
    <p>We have significant experience advising clients on complex securities law matters.We have advised on domestic and international cross-border transactions including overseas IPOs.</p>
    <p>

    <li>Structured Finance</li>
    <li>Take-overs</li>
    <li>Underwriting Agreements</li>
    <li>Warrants</li>
</div>
</div>



<div class="section">
<h1 id="mergersandacquisitions" ><br><br><br><br><br>Mergers & Acquisitions</h1><br>
<div id="content_services">

    <li>Corporate Reorganisations</li>
    <li>Due Diligence</li>
    <li>Joint Venture</li>
    <li>Privatisations</li>
    <li>Private Equity & Venture Capital</li>
    <li>Share & Business Acquisitions</li>
    <li>Take-overs</li>
</div>
</div>

这是CSS：

/*/*Navigation menu services*/
 h3{
    font-family: futura;
 }
#navigation-block {
    position:relative;
    top:200px;
    left:200px;
    font-family: "Lucida Grande", Verdana, sans-serif;
}

#hide {
    position:absolute;
    top:30px;
    left:-190px;
}

ul#sliding-navigation
{
    list-style: none;
    font-size: .75em;
    margin: 30px 0;
    padding: 0;
}

ul#sliding-navigation li.sliding-element h3,
ul#sliding-navigation li.sliding-element a
{
    display: block;
    width: 150px;
    padding: 5px 18px;
    margin: 0;
    margin-bottom: 5px;
}

ul#sliding-navigation li.sliding-element h3
{
    color: #fff;
    background:#333 repeat-y;
    font-weight: normal;
}

ul#sliding-navigation li.sliding-element a
{
    color: #999;
    background:#222  repeat-y;
    border: 1px solid #1a1a1a;
    text-decoration: none;
    font-family: futura;
}

ul#sliding-navigation li.sliding-element a:hover { color: #BBA842; }

我应该做什么来更改每个#link 的活动链接。例如，当我点击并购，只有“并购”链接具有活动颜色，而不是所有链接颜色。

我也尝试创建类似 a:active 的东西，但不起作用。

ul#sliding-navigation li.sliding-element a:active { color: #BBA842; }

请有人有想法分享并帮助我。 谢谢

p/s： antindexer 刚刚解决了我的问题。所以我补充的是： 在 style.css 中，我添加：

li.active a
{
    color: #BBA842!important;

并在 html 文件中。我添加了 JavaScript

<script>
$(document).ready(function(){
    $('div#services_menu li').click(
        function(e)
        {
            $('div#services_menu li').removeClass('active');
            $(e.currentTarget).addClass('active');
        }
    );
});
</script>

我可以建议使用 jQuery。类似的东西this.

$(document).ready(function(){
$('div#services_menu li').click(
    function(e)
    {
        $('div#services_menu li').removeClass('active');
        $(e.currentTarget).addClass('active');
    }
);
});


li.active a
{
    color: #BBA842!important;
}

因为，首先您正在使用锚链接，并且您希望使其动态。如果任何其他人可以建议使用 CSS 的解决方案，我将不胜感激。
