In `@frontend/src/components/shared/Backtotop.jsx`:
- Around line 7-15: The toggleVisibility function in the useEffect hook is only
called when a scroll event occurs, leaving the button in a stale state on
initial render if the page has already scrolled past 300px. Call the
toggleVisibility function immediately within the useEffect before adding the
event listener to ensure the button visibility is correctly set based on the
current scroll position when the component first mounts.
- Around line 25-39: The button element in the Backtotop component remains
keyboard-focusable even when hidden because pointer-events-none only prevents
mouse interactions, not keyboard focus. Add a disabled attribute or
tabIndex={-1} to the button that is conditionally applied based on the visible
state: when visible is false, either set disabled={true} or tabIndex={-1} to
remove the button from the keyboard tab order and prevent it from being
accidentally focused.
- Line 2: The Backtotop component imports FaArrowUp from react-icons/fa6, but
react-icons is not declared as a dependency in the frontend package
configuration. To fix this, either add react-icons to the frontend dependencies
in package.json, or replace the import statement in Backtotop.jsx to use
lucide-react (which is already a declared dependency) instead, updating the icon
reference from FaArrowUp to the corresponding lucide-react arrow icon (such as
ArrowUp).

In `@frontend/src/components/shared/Backtotop.jsx`:
- Around line 26-37: The conditional return of null at the start of the render
logic removes the button from the DOM entirely when invisible, preventing the
fade-in/fade-out animation from working. Keep the button mounted at all times
and instead conditionally apply opacity, transform (like translate), and
pointer-events classes based on the visible state. When visible is false, use
classes to fade out (opacity-0), move the element slightly (translate-y), and
disable interactions (pointer-events-none). Ensure the existing transition-all
and duration-300 classes remain active so the CSS changes smoothly animate.
Additionally, add aria-hidden="true" when the button is hidden to keep it
non-focusable for screen readers.
