I am a Year 12 Digital Solutions student editing a simple HTML, CSS and JavaScript project.

File I am editing: [index.html / style.css / script.js]

Here is my current code:
[paste code here]

I want it to:
[explain the feature or fix you want]

Please:
1. Explain what needs to change in simple language.
2. Give me the full updated code for this one file.
3. Tell me which file to paste it into.
4. Do not remove existing features unless it is necessary.
5. Add comments only where they help me understand the code.
