Right, that’s it for now. After some experimentation, I discovered that I couldn’t banish the left-hand column after all. It didn’t look right (to me) without anything on that side. I did, however, make it smaller so that it wasn’t as noticeable – and added the column effect to my journal entries. Likewise, the page “footer”, with my links, also stayed the same in the end.
It’s late now, and I’m starting to lose focus. I’d better stop while I’m ahead. Further tweaks will have to wait until later.
