点击后保持菜单按钮有效

Question

目前，当我将鼠标悬停在我的按钮上时，它会改变颜色，这是完美的。它从浅蓝色变为深蓝色。当我点击菜单上的一个按钮时，我希望它保持深蓝色，具体取决于我所在的页面。这可能吗？如果我需要添加更多代码，请告诉我

HTML

<nav>
    <ul id="menu_wrap" class="Blue">
        <li class="button"><a href="Default.aspx" id="manage">Manage Report</a></li>
        <li class="button"><a href="Item.aspx">Create New Item</a></li>
        <li class="button"><a href="CloneReport.aspx">Clone Report</a></li>

    </ul>
</nav>
