Design 3
User Guide:
Tour.html is intended to be a prototype only for design display purpose. User interface navigation is similar to design 1.
Design Note:
This design is intended for the tour pages to go under the main search section. Thus its header design is very similar to Google's tools page.
The main highlight of this design is that the navigation for the tour is moved from the left-nav to the top of the page. This gives it a more fun design as well as enabling the tours page to have more "independence" from the rest of the search sites.
Pros:
-Easy maintenance.
-The tour.html (overview) page does not have too many competing headers like design 1.
Cons:
-Nav design is fun but may not fall under general Google design.
