Hi Marius,
Thank you! I've tried to change it, but I'm not sure where to do this. I've copied your text into mine (with my file name) in Lay options > Custom CSS & HTML, and in Customize > Extra CSS.
Which one is the correct section?
For now, both didn't work. Sorry, I don't really have experience with CSS so probably I'm missing something totally logic.
Best!
