FEAT : return to top button added (enhancement) (JhaSourav07#547)

JhaSourav07 · web-flow · commit b7b4c79bed0d · 2026-05-27T19:09:59.000+05:30
## Description Fixes JhaSourav07#539 This PR implements a responsive and accessible “Back to Top” button across the web application to improve navigation and user experience on long-scroll pages. Previously, users had to manually scroll back to the top after navigating through lengthy sections, which reduced usability, especially on mobile devices and content-heavy pages. This fix introduces a floating action button that appears after scrolling beyond a certain threshold and smoothly returns the user to the top of the page while preserving the existing UI behavior and responsiveness. ## Changes Implemented Added a reusable Back to Top component with: - Smooth scrolling functionality - Scroll position detection - Conditional rendering after a scroll threshold - Responsive positioning for mobile and desktop - Light/Dark theme compatibility - Accessibility support using aria-labels and keyboard focus handling ## Added defensive UI handling for: Small screen responsiveness Preventing overlap with important UI elements Consistent visibility across different layouts ## Root Cause The application previously lacked a quick navigation mechanism for returning to the top of long pages: // No dedicated return-to-top functionality existed Because of this: users relied on manual scrolling navigation became inconvenient on long pages mobile usability was reduced overall UX consistency was impacted ## Validation Successfully verified with: npm run test npm run lint npm run build ## Test Results 1. All test suites passed successfully 2. Production build compiled successfully 3. Verified responsive behavior across screen sizes 4. Verified smooth scrolling functionality 5.
