Ask HN: is there a site-builder for the now-typical style of web product sites?

Most of the new web based software-as-a-service products / companies have a site with a very similar style. That style seems to have been pioneered originally by 37 signals. Do you know the style I mean? Typically one large page that is scrolled down through various sections, each section communicating a small number of marketing points/features/benefits. At the bottom there is the now-typical pricing panel. Often each panel will have a different color, sometimes an image as a background in the panel. So two questions/requests: 1: is there a standard "site builder" anywhere that allows creation of pages that follow this seeming standard layout? Ideally something that just allows fields to be filled in and boom out comes the site. 2: if you know any examples of sites that follow this style/layout please post a link below. It would be great to have a collection of examples of sites that are in this style.
