A header -- part of "main" div class

Text here -- part of "main" div class

This is a hyperlink -- part of "nav" div class

Text in here too -- part of "nav" div class

Info on the test: In the actual html file, the "main" div class parts are on top of the "nav" div class parts. However, the xhtml file contains a style for the xhtml body, that reverses the order of these two div classes.
