Add Code Copy Section for Projects

Implement a feature that allows users to easily copy HTML, CSS, and JavaScript code snippets from project examples. This section should include:

• A visually distinct code block for each language (HTML, CSS, JS).
• A 'Copy' button for each code block, enabling users to quickly copy the code to their clipboard.
• Optional: Add syntax highlighting for better readability.

This feature will enhance the user experience by making code examples more accessible and easier to use.
