Create a copy button for the blog post

"Add a 'Copy to Clipboard' button to the blog post to allow users to easily copy the content or a specific section of the post. This functionality improves user experience by eliminating the need for manual copying, especially for text like code snippets, quotes, or key points. Ensure the button has a clear label, intuitive design, and visual feedback (e.g., a 'Copied!' message) after the action is completed. Test the button across devices and browsers for compatibility and responsiveness."
