It seems like you are having issues with a JavaScript code not executing properly. Here are some steps you can take to debug: 1. Check if the DOM elements you are targeting in your JavaScript exist in your HTML code. Make sure the class names match exactly. 2. Check if there are any errors being thrown in the console. You can open the console in your browser and refresh the page to see if there are any errors. 3. Double-check that the script file path is correct and that the script is actually being loaded. You can do this by checking the Network tab in your browser's dev tools. 4. Lastly, you can try adding console.log statements in your JavaScript code to see if it is being executed at all. For example, you can add a console.log inside the event listener to see if it's being triggered when you click on the burger menu icon. Hope that helps! Let me know if you have any other questions.
