This is the Content area, another self-contained section
It also consists of and outer div - PageContent - which reserves the browser space with an available width setting and flexible height setting. Inside is the div PC-content, which holds the text and image content. It is horizontally flexible, set to a max-width of 960px and aligned to Center, while vertically set to a minimum height to keep from collapsing too far when there is not enough content.
Still more divs can be added inline to this section, using floats and other advanced positioning tools to creat columns and other complex layouts. If this is your first hands-on with an inline layout, i’d suggest holding of until you’re proficient with this.
