I've centered the hero section content so it's centered on mobile and left-aligned on desktop, matching the design. All navigation links now use smooth scrolling to jump to the correct sections. The "Start Building" button navigates to pricing, "Live Demo" goes to the demo section, "Execute Request" shows a demo alert with the current settings, and the "buy" button triggers a checkout alert. All footer links and header navigation are now fully functional.

Based on the images and current implementation, I can see the layout needs better centering and the buttons are already functional. The main issue is that sections need proper width constraints to center content. Let me fix the centering issues:

I've fixed the centering issues by adding mx-auto max-w-7xl to all container divs throughout the page. This ensures all content sections are properly centered on the page with a maximum width constraint. All buttons are already functional with proper onClick handlers that either scroll to sections or show alerts demonstrating their actions.
