Yep, the layout is right. The issue is whether I need to have a wrapper that runs through the whole page to support content in the header and the footer so it matches the dimensions of the main content.
I think I get it. The content of the header and footer is also going to be limited to 1140 or so, is that it?
In that case, no…and yes. You don’t wrap everything just add divs inside the header-container and footer-container, limit them to the specified width and center them. That way your header-container and footer-container become…erm, containers. :)
