I've had my dulcimer site, http://mp-dulcimer.com, for a few years and have decided that some of the content would be better suited to a blog than static pages. I've put the blog here: http://mp-dulcimer.com/blog/
I would like to modify one of the templates to match my site. It's got a background image with a left-side border. I want the blog content and sidebar to clear that border no matter what size the window is, and ideally I'd like to avoid having horizontal scroll bars appear when people resize the window.
Any suggestions on how to go about doing this? I've started messing around with the default theme, but from reading other posts about margins it looks like maybe I ought to try customizing the classic instead.
