I've been playing with WordPress for a couple years and understand PHP and CSS basics. (For the most part) Enough that I can modify most themes to suit my needs.
I've had enough with editing and wanted to build my own theme/style for my site. I found the sandbox theme. http://www.plaintxt.org/themes/sandbox/ it seems to be awesome. Like the author said. A canvas for CSS... I have created a CSS sheet and really like the style I've created. I validated the css and only found 1 parsing error. So I know that's clean.
My issue - the sidebar moves up and down depending on what post I open on the main page. I've set the content width. SO now I'm lost. I'm a good reader. I'm sure this has been answered before. If you would be so kind to post links to help I'd greatly appreciate it!
