Responsive E-commerce Website Template

I need a fresh, responsive website template built specifically for an e-commerce store. The focus is on clean, modern visuals that highlight products, load quickly, and adapt seamlessly from mobile to widescreen.

Please deliver well-structured, W3C-valid HTML5, CSS3, and lightweight JavaScript so my developers can wire it to the backend without rework. A reusable component system—headers, navigation, product grids, modals, and a streamlined checkout flow—will make future updates painless. Alongside the coded template, include the original design source (Figma, Sketch, or XD) and a concise style guide covering colour palette, typography, and spacing rules.

Acceptance criteria
• Lighthouse scores of 90+ for performance and accessibility
• Consistent rendering on the latest Chrome, Safari, Firefox, Edge, and mobile browsers
• Clear commenting and folder structure for easy hand-off

If you’ve crafted storefront themes before and can share a live link or code snippet, that will help me choose quickly. I’m ready to move forward as soon as the right fit appears.
