I'm discouraged, sir. I tried adding an explicit height to the wrappers, but the result's remaining the same -- lame display in FF and correct in Chrome. With or without fixed height.

If you just try it with FF on your side to reassure I'm not breaking down for a stupid reason.

Thnks a bunch! I got that... But it remains unclear why Chrome still displays it as before. I believe I have the cache disabled in all my browsers.

Hi, everyone!

Let me publish a little "discovery" based on a flip card w3cshools TryIt:

As I apply one more wrapper to the flipcad front&back DIVs with no other changes, the result becomes inadequate in FireFox. 

All chromium-based browsers render it okay.

Layout remains solid and its logic still intact. So why???!!!
