Boy, I hate gmail at the moment. In mailbuild, the Old School - Complex template does not come close to rendering correctly.
I'm not sure how it can. According to the CSS Compatibility Chart, gmail does NOT allow for <style> elements in the head or the body, nor link elements.
Or even (the primary issue) does not support the css property background-image or background-repeat.
The Old School - Complex template depends heavily on those two properties and it just does NOT work in gmail.
Anybody have any suggestions other than using a different template? I do like this template a lot, but gmail won't render even the little bit of css needed to look good (heck, even look readable) in gmail.
