Design a simple, interactive web page suitable for learning HTML, CSS, and JavaScript. The page should include: A header with a title. A navigation bar with 2–3 links (they don't need to work). A main section with: A text paragraph. A button that changes the text or color when clicked (use JavaScript). A footer with some placeholder text. Use simple, clean HTML, CSS for styling (colors, spacing, basic layout), and JavaScript for basic interactivity. Make the code easy to read and modify for practice.*
