Full Width Not Showing

What seems to be missing? It looks like I’m seeing everything that’s supposed to be on the page, and no horizontal scroll bar appears. Or are your referring to the red margins on either side of the main content area? The main content area is set to a maximum width of 1000px, so if the browser is wider than 1000px you’re going to see those margins. Plus, any narrower width and you’ll still have a 2em margin on the sides, based on the CSS settings. Were you expecting no margins at all?
