To dynamically add an "active" CSS class to the navigation menu based on the current page, you typically need to determine the active page within your application and conditionally apply the "active" class to the corresponding navigation link.Here's a general example using vanilla JavaScript for a simple scenario:```html<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <style> /* Your basic navigation styles */ nav { background-color: #333; padding: 10px; } nav a { color: white; text-decoration: none; padding: 5px; margin: 0 10px; } /* Active link styles */ nav a.active { background-color: lightcoral; } </style> <title>Dynamic Active Class</title></head><body> <nav> <a href="/" id="homeLink">Home</a> <a href="/about" id="aboutLink">About</a> <a href="/contact" id="contactLink">Contact</a> </nav> <script> document.addEventListener('DOMContentLoaded', function () { // Get the current page URL const currentPageUrl = window.location.pathname; // Get all navigation links const navLinks = document.querySelectorAll('nav a'); // Loop through each link and check if it matches the current page navLinks.forEach(function (link) { const linkUrl = link.getAttribute('href'); if (currentPageUrl === linkUrl) { // Add the "active" class to the matching link link.classList.add('active'); } }); }); </script></body></html>```In this example:- The JavaScript code runs when the DOM is fully loaded (`DOMContentLoaded` event).- It retrieves the current page URL using `window.location.pathname`.- It loops through each navigation link and compares its `href` attribute with the current page URL.- If a match is found, the "active" class is added to the corresponding navigation link.This is a basic example, and in a more complex application or framework (such as Angular, React, or Vue.js), you may have more advanced routing mechanisms that handle this for you. If you are using a specific framework, let me know, and I can provide more targeted guidance. read less
