I have a fully-designed header in my nopCommerce store; what’s missing is true responsiveness. I need you to take the existing HTML/CSS (no redesign needed) and make sure it adapts perfectly on mobile, tablet and desktop screens. Key focus areas are the logo and overall branding block, the navigation menu and the search bar. They should scale, stack or collapse smoothly without breaking layout or affecting load time. All work will be done remotely, so you’ll receive the current theme files and a staging URL to test against. Deliverables • Updated header markup and style sheets integrated into the current nopCommerce theme • Clean, well-commented code that follows nopCommerce best practices • Visual confirmation (screenshots or short clip) showing flawless display on common breakpoints for mobile, tablet and desktop • Brief hand-off notes so I can maintain the changes in future upgrades If you’ve already handled front-end tweaks in nopCommerce and can turn this around quickly, let’s get started.
