HTML Business Promotion Website

I need a clean, professional website coded in pure HTML (with supporting CSS and a touch of lightweight JavaScript where it makes sense) that will act as the central hub for promoting my business. The heart of the site is a set of pages showcasing our product and service details—think engaging descriptions, feature highlights, pricing blocks, and strong calls-to-action.

While those pages are the priority, the layout should leave room for me to add company information and customer testimonials later, so the navigation and visual hierarchy must be flexible. I have all copy and images ready; your role is to translate them into a fast-loading, cross-browser-compatible experience that feels polished on desktop, tablet, and mobile.

Visual style should be modern and trustworthy. If you have a preferred framework such as Bootstrap 5 or Tailwind, let me know, but I’m fine with a custom CSS approach as long as it stays maintainable. Please keep code well-commented and organised so I can make simple text updates on my own.

Deliverables:
• Fully responsive multi-page HTML site, zipped and ready to upload
• Linked style sheet(s) and any external assets clearly referenced
• A brief read-me explaining folder structure, how to update content, and any dependencies

I consider the project complete once every page renders correctly in the latest versions of Chrome, Firefox, Safari, and Edge, all internal links work, and Google Lighthouse scores green for performance and accessibility.
