Yeah, I'd just found the -160px and taken it out a few minutes ago. Actually getting closer. BUT, yes...absolute and relative positioning are a bit of a mystery for me.
The display: table-cell code came from some snippet I'd used on a splash page, I believe. I think it had to do with trying to display something the full height of the screen...but it's been awhile now so I'm not really sure :-( And that function certainly isn't something I want/need for *this* site.
Thank you for your patience and help.
