Thanks for testing and confirming.

Thanks for testing. I can confirm that once those two lines are removed, the classes are correctly found.
But my understanding is that those two lines are required. Is that correct?

The big question- is this a problem with my CSS or with Calibre? As theducks states, Sigil has no problems with those two lines being included.
