Thank you for your very specific instructions. It worked perfectly.
Two more questions:
Is there a way to make the columns slightly wider?
I would like put an image into each column but I’m having trouble with the sizing. I uploaded a test image and set it to thumbnail size but it is still too large. What is a size that will fit into each column without being cut off? I would like it to be a square.
