Well, thanks for the answer.

I tried as you said, removing the style and then on the parent (frame) set a
background role:

frame.setBackgroundRole(ColorRole.Shadow);

Now, the scroll area is the right color (some black) but the parent still
has the default gray of the window. It hasn't changed its background. I
don't know why.

Anyway, I used another technique to achieve my goal. I wanted to display a
text on several lines and be able to scroll it if needed. Instead of putting
a label in a scroll area, I simply used QPlainTextEdit:
- in read only mode
- with no frameShape (NoFrame)
- with a transparent background color. I simply used the following style
sheet:

#content {

background-color: rgba(255, 255, 255, 0);

}


Now that I write this e-mail, I realize that the same works for the scroll
area. Just set a transparent background color :)
