Is it possible to put a telephone number and/or an address somewhere on the website? Possibly in the header or footer. Or anywhere?
Yes, you can use the footer widgets to add any text information you want, just like we did on our demo: http://themes.opendept.net/hemma-elegant/
Thanks for this. The link takes me to a theme called "Hemma" which seems to be a standard footer widget creation. My question was in relation to the Retro theme. I can't seem to see where I'd make a footer.
Oh, I am sorry for misunderstanding!
I am afraid there isn't such an option, I am sorry. Those are pre-built section so you might need to use the child theme and add some extra information in the part-contact.php file or any other file where you want to display them.
