**In this code, we create a mobile-friendly password generator with a responsive layout. It includes an input field for the password length, a "Generate Password" button, and a display area to show the generated password.

The JavaScript code handles generating the password based on the specified length and using a character set of uppercase letters, lowercase letters, digits, and special characters. The generated password is displayed in the designated area.

Feel free to customize the design and add more features like password strength indicators or additional character options to make it even more professional and user-friendly.**
