Step 3: Build the Web App (40 min)
Now comes the fun part! Let’s build a simple to-do list app.
-
HTML Structure:
- In
index.html, create a simple form for adding tasks and a list to display them. Use Copilot to generate the form elements.
<body> <h1>My To-Do List</h1> <form id="taskForm"> <input type="text" id="taskInput" placeholder="Add a new task..."> <button type="submit">Add</button> </form> <ul id="taskList"></ul> </body> - In
-
JavaScript Functionality:
- In
script.js, write a function to handle form submission and add tasks to the list. Start typing comments, and let Copilot fill in the code.
document.getElementById('taskForm').addEventListener('submit', function (e) { e.preventDefault(); const task = document.getElementById('taskInput').value; // Add task to list }); - In
-
Style Your App:
- Use Copilot to generate CSS rules that improve the look of your app, like margins, padding, and colors.
Step 4: Test Your App (20 min)
- Open in Browser: Open
index.htmlin your browser to see your app in action. - Debugging: If something doesn’t work, use the Developer Tools (F12) to debug. You can ask Copilot for help by typing comments about what you need.
Troubleshooting
- Common Issues: If tasks aren’t appearing, check your JavaScript console for errors. Copilot can help you debug by suggesting fixes.
- Styling Not Applying: Ensure you link your CSS file correctly in
index.html.
