📝 Walkthrough

Walkthrough

Replaces the per-row navigation icon with a trash button and adds a handler that removes a quiz by index from localStorage ("last5Quizzes") and component state; the trash button stops event propagation to preserve existing row click behavior.

Poem

🐰 A tiny trash, a nimble paw,
Tap once and watch a quiz withdraw,
Local history tidied, neat and sly,
One less score beneath the sky,
Hopped away — a clean-up sigh.

In `@eduaid_web/src/pages/Previous.jsx`:
- Around line 93-100: The delete button is icon-only and lacks an accessible
name; update the button that calls handleDeleteQuiz(index) (the button wrapping
the FaTrash icon) to provide an accessible label by adding an aria-label (e.g.,
aria-label="Delete quiz") or include visually hidden text inside the button so
screen readers announce its purpose while keeping the FaTrash icon visible.
