Hi. I'm a total newbie to Webstudio, so apologies in advance for this question as I'm sure I've probably overlooked something. I'm creating a hero section on my homepage and have a added a section to the body. I'm trying to add a background image to this but cant see any way of doing this from the style or settings panels on the righthandside - there is nothing in "Backgrounds", the most obvious place. How do I go about doing this? Many thanks.
