Thank’s so much for your reply. I did all you explained. But it changed only the background of the title on the bootstrap slider.
Id like, if is it possible, to make transparent because i made the slides with a white part under the picture. So the title and the description should be with a transparent background.

For the mobile version all works correctly but the title and description are in the center of the slide. I added your code but nothing changed. Maybe i wrong something.
I can’t reduce the pictures because of the motivations I explained.

Help me 🙂

thank’s so much!
