I uploaded the background image on a section (after giving it a class), set it to "cover", but it doesn't appear.
I checked the tutorial again, but fail to see what I do wrong.
What did I forget to do ?
Should I put it into a container inside the section ?
Edit : it is linked to the placement of a container with "position:absolute"
-> I just want a section with a background image, and some text vertically centered in that section.
That should be simple, but l'm blocked
