[🐛 Bug Report] Correct Guide Flashcards on Firefox

[susanthgit]

Hi,

the flashcards dont work properly on FIrefox, the solution text are overlapped by the question text, which makes it hard to read at times. This happend on multiple Win11 machines and FF versions.
I know the site surely is optimized towards Chromium, but maybe you can look this :)
Your work is outstand, thank you so much!

Hey Jens — thank you, this is a real one and a great catch. 🙏

You're right, and I've reproduced it: on Firefox the flip card doesn't hide its back side, so when you reveal the answer the (mirror-reversed) question text overlaps it and makes it unreadable. Chromium hides it correctly, which is why it only bites on Firefox. It's on my end, not your setup.

Right now: the quickest unblock is to view that exam in desktop Chrome or Edge — the flashcards render cleanly there while I sort the fix.

The fix: I've got a small change working in current Firefox and Chrome; I'm validating it across more browser versions (incl. Safari) before I deploy, because that flashcard is shared across every exam and I won't risk breaking it for everyone to fix it for one. I'll come back to this thread the moment it's live.

If you can, tell me your Firefox version and OS — helps me verify against the same build. And thanks for the kind words, genuinely. 🙂

Update, Jens — this is fixed and live. ✅

Digging in, it turned out to be broader than just Firefox: the flip card wasn't reliably hiding its reverse side on Firefox and Safari/iOS (Chrome and Edge were fine), so the mirrored text bled through and overlapped. I reworked how the card hides its back face so it's solid across all of them — and left Chrome/Edge's behaviour exactly as it was.

I tested it across Chromium, Firefox and WebKit (Safari's engine) — flipping both directions, mid-animation, dark mode, mobile, print and reduced-motion — all clean now. Give it a hard refresh (Ctrl+F5) on your Win11 + Firefox setup and the flashcards should read perfectly.

Thanks again for flagging it — you actually surfaced a bug that was hitting Safari/iOS users too. Genuinely appreciated. 🙏
