激活导航栏

问：

我正在尝试使导航栏在我们所在的页面上处于活动状态（例如突出显示）。 例如，如果我们在主页中，它将突出显示主页按钮。例如，当我们在新闻页面中时，我试图让它突出显示导航栏上的新闻按钮

这是我的html代码：

    <nav>
        <input type="checkbox" id="check">
        <label for="check" class="checkbtn">
            <div class="container">
                <div class="hamburger" id="hamburger">
                    <div>
                        <span class="line-1"></span>
                        <span class="line-2"></span>
                        <span class="line-3"></span>
                    </div>
                </div>
            </div>
        

            </div>
        </label>
        <script src="nav.js"></script>
        <label class="logo"><a href="index.html">JR-Koders</a></label>
        <ul>
            <li><a href="index.html" class="text active">Home</a></li>
            <li><a href="nav.html" class="text" id="my-news">News</a></li>
            <li><a href="#j-koder" class="text">J-Koder</a></li>
            <li><a href="#r-koder" class="text">R-Koder</a></li>
            <li><a href="#Koders" class="text">Koders</a></li>
            <li><a href="#search" id="my-search"><i class="fa fa-search"></i></a></li>
        </ul>
    </nav>

这是我的CSS代码：
