NopCommerce UX Front-End Overhaul

I run an active NopCommerce store whose business logic and plug-ins are already performing perfectly, so I’m looking only for a front-end facelift. Your task is to replace the current theme’s HTML markup and CSS so the site feels noticeably easier to navigate, visually fresher, and fully responsive—while leaving every C# controller, model, service, and database call untouched. What I want to see • Cleaner, more intuitive navigation that guides shoppers to products in fewer clicks. • A modern layout with balanced whitespace, harmonious typography, and improved product grid/list views. • Mobile-first responsiveness that renders flawlessly from phones to wide desktop monitors. • Consistent use of my existing brand colours, logo, and iconography so the new theme still “looks like us.” Tech context The store is on the latest NopCommerce LTS build. Razor views are the presentation layer you’ll be working with, and Sass is welcome if you compile it down to CSS in the final hand-off. No JavaScript framework migration is required, but feel free to enhance the UX with lightweight vanilla JS where helpful, provided it doesn’t break plug-ins. Deliverables 1. Updated .cshtml view files (only the markup sections you modify). 2. A new theme folder containing all CSS (or compiled CSS if using Sass), images, and supporting assets. 3. A short README that explains where each file lives and how to enable the theme. Acceptance criteria • All pages load without server-side errors and maintain existing route/url structure. • Google Lighthouse mobile performance score ≥ 90. • Visual regression testing shows no broken images or misplaced elements across the top 10 most-visited pages. • Checkout flow remains fully functional end-to-end. If you’ve revamped NopCommerce themes before—or have a strong track record in responsive e-commerce front-ends—let’s talk.
