Footer - Copy this React, Tailwind Component to your project

Create a footer section for a Learning Management System (LMS) website that seamlessly supports both dark and light modes. The footer should feature a clean and modern design with a dark background for dark mode and a light background for light mode. Include links to key sections such as "About Us," "Contact Support," "Privacy Policy," and "Terms of Service." Ensure there is space for social media icons and a newsletter sign up form, with clear, contrasting text for readability in both modes. Additionally, incorporate a subtle divider to distinguish the footer from the main content, and ensure that all elements are responsive and accessible.
