I'll convert the German roofing landing page from React to pure HTML+CSS+JS. Based on the screenshot, I can see it's a professional roofing company website with a clean blue and white design.

I've successfully converted the German roofing landing page from React to pure HTML, CSS, and JavaScript. The converted version includes:

Key Features:

• Responsive design that works on all devices
• Professional German roofing company layout
• Interactive navigation with smooth scrolling
• Quote request modal
• Contact form functionality
• Mobile-friendly hamburger menu
• Scroll animations and effects
• Phone number formatting

Sections Included:

• Header with navigation and phone button
• Hero section with call-to-action buttons
• Services section with 4 main offerings
• About section with company information
• Contact section with form
• Footer with links and company info

Interactive Elements:

The code is organized into three separate files (HTML, CSS, JS) as requested and maintains the same professional appearance and functionality as the original React version. You can download these files and host them on any web server or static hosting service.
