The site I am currently working on has a few pages that are jammed full of content, and a few that aren't...in fact they are boarder line empty. So I have done some digging around and I can't quite make sense of the 100% height value. Everything I have read is confusing me as they seem to come from different time frames and come up with some info about css, so people talk about java... It seems to have something to do with the body container, main wrapper and then the content wrapper. I have an overflow:hidden in my css will that make any difference? Is there a tutorial someone can point me to, or just explain it a little.... I am getting confused.
