How this works

The large decorative question number uses a very high font-size at extremely low opacity (rgba(234,179,8,.07)) — it acts as a background texture rather than readable text. A category dot indicator uses a small ::before pseudo-element styled as a 6px circle, avoiding a separate HTML element just for the dot.

The answer back face uses a radial-gradient ::before pseudo positioned at 50% 30% to create a subtle green spotlight behind the answer text. The score row reuses the flex stat-component pattern seen throughout the collection, confirming that design tokens and layouts compose cleanly across different card contexts.

Make it yours

  • Add a timer that auto-flips after 10 seconds using a setTimeout class toggle — cancel it if the user hovers first.
  • Wire the option buttons as <button> elements with a JS click handler that flips the card and applies a green or red highlight to the selected option.
  • Change the star difficulty rating by toggling the .empty class on the five .fc-07__star spans from 1-star to 5-star.
  • Create a multi-card quiz by nesting multiple scenes in a grid and showing one at a time with next/prev buttons that swap display.
  • Add a progress bar beneath the card that animates from 0% to 100% over the question dwell period using a single @keyframes width rule.

Gotchas — read before shipping

  • Multiple-choice options use :hover to highlight — on touch devices this creates a tap-highlight-then-flip conflict; use a JS click handler for touch.
  • The decorative large question number should carry aria-hidden="true" so screen readers skip it and go straight to the question text.
  • Flip transition timing should be at least 0.6s to prevent accidental glimpses of the answer when a user clicks near the card edge.
