For This Project You Will Be Writing Most Of Your Code Injsappjsru For this project, you will be writing most of your code in js/app.js. Link your app.js file in your HTML. Build out your HTML with at least four content sections. Design your navigation menu to interact with these sections. The functionality will include detecting when a section is in the viewport, highlighting the active section's navigation item, and enabling smooth scrolling to sections when navigation items are clicked. Examine your index.html for element IDs, classes, and data attributes. Use this information to generate a dynamic unordered list in HTML representing your navigation menu. Think about how to test whether a section is within the viewport using the .getBoundingClientRect() method. Implement event listeners for scrolling to update the active navigation item based on the section in view. Use classList methods to add or remove CSS classes to highlight the active navigation link and section. Ensure that clicking a navigation item smoothly scrolls to the corresponding section.

Building an interactive and responsive navigation system for a webpage involves multiple steps, including DOM manipulation, event handling, and application of CSS classes to enhance user experience. This paper discusses the creation of a dynamic navigation menu linked to multiple content sections, active state highlighting based on viewport position, and smooth scrolling functionality, primarily using JavaScript, specifically within the js/app.js file. Firstly, establishing the HTML structure is crucial. The webpage should contain at least four distinct content sections, each identified with unique IDs, classes, and possibly data attributes. These identifiers allow JavaScript to target specific sections for generating the navigation menu dynamically and determining their respective positions relative to the viewport. The initial setup involves creating static or template-based content sections and a placeholder element for the navigation menu, often an unordered list (). The navigation menu's structure can be generated by traversing the sections using JavaScript, creating list items () with anchor tags () that link to respective section IDs, and appending these items to the menu container. Next, the core functionality involves detecting which section is currently visible in the viewport. This is achieved with the .getBoundingClientRect() method, which returns the size of an element and its position relative to the viewport. During scroll events, JavaScript evaluates each section’s bounding rectangle; if its top is within a specific threshold (e.g., between 0 and window.innerHeight), it is considered the active section. The script then updates the navigation menu by adding an 'active' CSS class to the corresponding list item and highlighting the section itself, often through adding or removing classes in classList. The script must also handle user clicks on navigation items. Event listeners are attached to each navigation link, intercepting default jump behavior, and
