I need a polished, multi-page website template ready for agencies, startups, and corporate brands. The package has to include six fully coded pages—Home, About, Services, Contact, Marketing, and Strategy—built with clean HTML5, semantic markup, and a single, well-organised CSS file that relies on modern Flexbox/Grid. The layout must adapt seamlessly to desktop, tablet, and mobile screens, meeting current accessibility guidelines and scoring 90+ in a Lighthouse audit for performance and best practices. Populate each page with premium, royalty-free images and placeholder copy so that swapping in real content is effortless. Subtle hover effects or lightweight scroll animations are welcome so long as they remain fast and unobtrusive. Acceptance criteria: • Six individual HTML files sharing a consistent header, navigation, and footer • One global CSS (plus any vendor files) that uses variables for quick theming • Optimised, commercially licensed imagery embedded and delivered in WebP/PNG as appropriate • Responsive behaviour confirmed across Chrome, Safari, Firefox, and Edge • All code W3C-compliant, neatly commented, and handed over in a zipped folder with a concise README explaining structure, customisation steps, and asset sources Once complete, I should be able to plug in branding colours, swap text, and launch without extra development.
