Responsive Feature Navbar - Copy this Html, Bootstrap Component to your project

I am looking to generate a responsive navbar code using a different AI tool. The navbar should adapt well to various screen sizes, including mobile, tablet, and desktop. It should have a clean, modern design with links that are easy to interact with. I prefer a simple dropdown menu for mobile views and smooth transitions between elements. The code should be well structured, using HTML, CSS, and possibly JavaScript. Please ensure compatibility with major browsers. I would like this to be optimized for fast load times.
