Re: Rate my design outta 10 please :)
The gap is still there. The content size properties are good -- the nav and the content are always the same height now, so that part's great, but you're still using raw percentages for the margin-left of the #sidebar and #box elements, and on a wide screen (again, mine is 1920px wide) that means there's going to be a gap between the two unless the width is also set in percent.
Try the negative margin trick. It will work on all screen sizes.
