1. Is it possible to show / hide the headline in hover (hidden, then showing in hover).
2. Is it possible to align the headline? (vertical & horizontally)
And yes, you’re right, the show/hide feature fits with Overlay style 2, sorry I didn’t realise before.
What about aligning headlines? I mean, when displaying over the image, would it be possible to align them? They show off sticked to the top and centered by default.
