Thanks Tom, I’ll give it a go.
P.S. I have been experimenting with the site library. It’s great but I reckon it would really help if they all had a page explaining what was going on and a shopping list of the required picture sizes. An example would be the pagebuilder-free blog site with the header at the left. Quick installation instruction including how it was done, how to adjust it and how to add to the social icons and activate the newsletter link. I did figure it all out eventually but brief instructions on where to look for the settings would have been welcome. Also educational.
